electric cars are all automatic
They aren’t, really. They don’t actually change gears, if you want to go backwards you spin the motor backwards.

And of course all shit electric cars are all automatic. It’s part of the NWO agenda. They want to force us all into electric, automatic cars, Over my dead body! A car that does not produce smelly fumes when driving is not a real car. What I am supposed to smell when walking in the city? Air? Fucking dumb. On top of that they make no sound! There’s nothing to tune up to make my car sound like a racing machine. How I’m supposed to let everyone know I have a small dick if I can’t rev my engine all the time? Not me mention electric cars don’t emit CO2 so I can’t lock myself in a garage with the engine running and kill myself when I realize that no one is impressed by my car and my dick is still tiny. Absurd!

And no, you can’t roll start them.
I imagine you “can”, it’s just not very effective. Like, if they allowed you to switch it to regenerative breaking and let it roll down a hill. The problem is you can’t get out any more energy than you put in. So if the battery is dead and you roll down the hill you won’t be able to rull any farther up the other side than you started (even less when you factor in mechanical -> electrical -> mechanical. You’d probably better off putting it in neutral [if that’s a thing for electric cars] and just let it roll)
zurohki@aussie.zone 11 months ago
No, you actually can’t.
For safety reasons, the 400V main battery isn’t hardwired to the car. There’s a couple of contactors powered by the 12V battery that connect it to the car.
If your 12V battery dies, the contactors open and the car is completely dead. You have to jump it or replace the 12V battery, then the contactors pull in, then the main battery can start charging the 12V.
Even plugging it in doesn’t work - the car won’t take a charge if the electronics are dead.
If the main battery is dead but the 12V hasn’t died yet, you can try regenning down a hill or plugging in or whatever. But if you lose the 12V, the car’s bricked.

just bridge them with a screw driver
bitwaba@lemmy.world 11 months ago
Yeah, obviously there’s technical reasons why. I was just approaching the problem theoretically. And then showing why the theory is stupid. It makes sense that they would implement other things for safety, especially if avoiding them only enabled a completely useless solution to a dead battery.

tl;dr: my PHEV does change gears when in EV mode, as weird as it sounds
So, I drive a Hyundai Ioniq Plug-in Hybrid EV. It’s a hybrid with a larger battery so it can plug it in and drive full-EV on the battery for ~30 miles/50 kilometers. The freaky thing is that the EV motor is connected to the transmission, so it does switch gears sometimes and you can feel it when it does. Even freakier is that this also applies to regenerative braking: when you slow down from a high speed, you can sometimes feel it switching gears while you brake. That all isn’t too bad since it’s got a dual-clutch transmission and so it switches gears pretty quickly, but it can still be a bit freaky at times.
Additionally: there are some people who have converted antique cars to EVs, but to save money they didn’t touch the transmission and instead elected only to replace the engine. They still have manual transmissions in them, though I suppose you could probably just find a suitable gear to leave them on 100% of them time. Still, you can, in principle, switch gears on them.
azertyfun@sh.itjust.works 11 months ago
Typically I’ve seen people keep their car in 2nd (or reverse IIRC? That way your controller doesn’t have to support reverse and you don’t have to put in a new switch on the dash) in electric swaps. Also you don’t use the clutch pedal to start, only to change gears, which is a bit freaky when you’re not used to it.
On the highway there might be value in switching to a higher gear though, torque/efficiency curves aren’t perfectly flat even on electric motors. I would be curious to know what gains would be had on a modern electric platform like an ID.3 if one was to put in a cheap sequential/manual transmission (for all I know the efficiency gains would not offset the additional losses from the clutch and gearbox, and even if they are some gains I’m sure that they do not make up for the inconvenience/lack of comfort of a MT).

Some have multiple speeds. I think the Porsche has 2 speeds for quick acceleration.

Honestly the only issue I have with electric car sound, is that in the country side animals, listin for your engine. So silent electric cars make it all the more likely that your gonna hit a bear. I’m not even asking for them to be deafeningly loud. Other than that my only problem with electric cars in general, is that they are soo overall boring. The Tesla models are just generic car design smoothed over. At least the Prius has a neat double rear windshield. Honestly the only electric car I’ve been thinking of getting, are those new 2cevs that are being reproduced, but electric. The only fun cool cars being made today are Supras and Miatas. Everything made in America just looks like a blow up car thats about to burst. Drm just worsens them further because now I can’t mod or enjoy fixing them. Electric cars are just infuriating because they are just a battery connected to some motors. The complicated part is a fuckin computer chip why is everything sealed. All this effort for a car that looks like a car shaped cum blob.

Mentioned this in another comment, but many regions now mandate that EVs have noisemakers built in which emit sound at low speeds (<40km/h or so).

Apparently all the deer around me are fuckin deaf going by what cares I’ve seen hit them.

I suppose different places have different animals. But in my home state at least, deer were only a problem when my folks got a f150. That ironically enough was extremely quiet. It was easily my familys most quite vehicle we had. And it was the only vehicle that had deer jumping in front of it and even hit a bear.
ExLisper@linux.community 11 months ago
I for one think that cars should be boring. And safe. Safe and boring. You want a fun car? Go to a racing track. You’re on a public road, sharing it with responsible people? Drive responsibly. Be boring. Shitload of people would still be alive today of everyone had a boring car and drove in a boring way.
creditCrazy@lemmy.world 11 months ago
I disagree because when we look at places like the Netherlands were they have driving alternatives ie bike, train and walk. Driving becomes more fun and the only people on the road are people who ether like driving or traveling long distances and driving accidents plumit. Compair that to amarica where driving is already boring, we have aggressive drivers, drunk driver and irresponsible drivers, and we have greater amounts of accidents. Because people who don’t enjoy driving are forced to drive and people who do enjoy driving have nowhere to go. It’s kinda like skateboarding with higher stakes. If you tear down skateparks, people who enjoy skateboarding with skate in public. Today we are expanding urban sprawl to the point that city’s are destroying the few race tracks that are left. So no duh hooners are going to hoon in public roads. The government destroyed the local track last year. So ultimately no I don’t think boring cars are the solution to bad driving. If anything it’s just gonna make it worse because no one cares about how well they drive it’s boring.

I’ve literally seen people post that they’d consider going electric if only it had an engine sound. Seriously, people who are old enough to have a drivers license want their car to go wroom wroom.
I get it. It’s the same reason all cars have a steering wheel, despite it being the most dangerous part of the interior. Joysticks just don’t give the same feel as when the captain steers the boat over the seven seas.
Wroom wroom, steer steer, wroooom, change gear while turning, push pedal, wroom wroom.
jukibom@lemmy.world 11 months ago
Steering wheels are enormous because that allows fine grain control, which you need at higher speeds. Switching lane at 70mph requires only very slight movement but turning the car around in a street you can go full lock.
A joystick would be fucking TERRIFYINGLY stupid lmao
filcuk@lemmy.zip 11 months ago
Some vehicles use steering by wire, which uses motors for i/o. This allows for steering sensitivity adjustments based on speed or wven preference.
jukibom@lemmy.world 11 months ago
True, but sensitivity is only half the story - the direct feedback of a wheel cannot be overstated
bstix@feddit.dk 11 months ago
No it’s not terribly stupid. Handicapped people already use other controllers without any issues.
A steering wheel is already electronically adjusted for speed. The servo will work just as well regardless of the controller device.
Along with lane assistance and other “self driving cars” it should be pretty evident that there is nothing dangerous about giving up the physical turny wheely kindergarten toy controller.
jukibom@lemmy.world 11 months ago
It’s not just about precision, it’s about feedback. Being directly connected to the drive train gives valuable feedback about the road and the front wheels - just because handicapped people have an alternative that they may use out of necessity does not mean it’s a better solution.
In a fully autonomous car, sure perhaps a simple manual system as a backup makes sense but we aren’t there yet. You are talking absolute nonsense, and I can only assume you haven’t ever driven a vehicle.
GiveMemes@jlai.lu 11 months ago
I mean the wheel is definitely the best control mechanism for driving… whether or not it’s dangerous, there’s a reason the best sim racers use wheels and not controllers and it’s that they provide vastly more control.
bstix@feddit.dk 11 months ago
I think it’s just a matter of getting used to it. Something like a playstation controller would be easy to learn for most people. People who play racing games seriously wouldn’t use a wheel and pedals. It’s just too slow.
I_dont_believe_it@lemmynsfw.com 11 months ago
Huh? People that use steering wheel and peddles for racing games have a serious advantage, it’s far more accurate, I have no idea what makes you think it’s too slow or what that’s even supposed to mean.
Most people use a controller for racing games because there’s no setup or space requirements and it’s what they’re used to. Plus a basic decent steering wheel setup is about three to four times the cost of a standard Xbox or PlayStation controller.
Sprucie@feddit.uk 11 months ago
But in a racing game the wheels can also twist from hard lock left to hard lock right in a millisecond, not sure that’s possible or desired in real life
WhiteHawk@lemmy.world 11 months ago
That is not true at all, unless the racing game is NFS or something. The people seriously playing racing sims all use wheels and pedals.
vonxylofon@lemmy.world 11 months ago
Clearly, you don’t frequent simracing communities.
FlyingSquid@lemmy.world 11 months ago
I mean, you can steer a submarine with it, am I right?
vithigar@lemmy.ca 11 months ago
I was extraordinarily glad to have a wheel when my power steering failed and found myself having to turn the car using the strength of my arms and the leverage of the wheel. A joystick would’ve made the vehicle literally impossible to steer.

It’d have to be a long joystick.

In many regions now it’s actually mandated that EVs make additional noise when moving at low speeds (less than 40km/h or so). There were concerns that quiet vehicles would have more pedestrian accidents.

There actually is an EV with engine sounds and a “manual transmission” from Toyota. According to ArsTechnica, it’s supposed to be pretty good:
