It becomes reliable if the car uses all the other sensors together with the GPS. Current German cars do that for their internal computers, for positioning, controlling their driving dynamics etc. Such systems are able to drive through several kilometers of tunnels and still know their own position with a deviation less than a meter, and afterwards adjust it again from GPS and mobile antennas etc.
But they usually don’t display this data on the spoedometer.
Comment on Do you need to adjust your speedometer if you change the size of your tires?
RegalPotoo@lemmy.world 4 weeks agoUsing GPS to drive the spedo/odo on a car seems like it wouldn’t be super reliable?

Not so good in a tunnel or surrounded by high rise, trees etc.

A lot of tunnels have GPS beacons to mitigate the issue of constellation blindness.

Can you tell me some tunnels that have GPS?

That’s why it’s not a thing and OP is wrong.
