Few things with the car analogy. You don’t purchase a care for a term. Even tho they come with a warranty. Cars have manufacturing standards, as do the regions they are legal to operate in; the existence of these standards is what substantiates lemon and bait and switch laws.

You’re forgetting impeachment. If someone commits crimes they can be impeached - and has been done despite recent top of mind events.

This is the same argument that has kept senators in congress for decades with no term limits.

You’re conflating changing people mid term with changing people at their regular term intervals. As an American you rarely experience elections outside their scheduled interval. As a Canadian I can assure you that elections do interrupt things especially when you have to go to the polls repeatedly. We had federal elections 2 years apart in 2019/2021 and it was largely a pointless expense that served only to reset the governments 5 year window to call the next election.

Also the new guy being worse is a bit of a “whataboutism”

No its not. Whataboutism is pointing the finger at someone else to deflect. Logically if we elected someone who is doing such a bad job that we need to recall them, it is possible we could do that again.

A higher barrier to recall would help the constant switching

I think thats the case. I’m Canadian and recall elections are possible for anyone given the constituants follow a multi step process leading to a recall vote.
