State department hand wringing that China is going to use the US trade agreements as they were designed is 
I fully expect them to redo these with "except china" clauses.
I've driven a lot of Bolts (but not owned one, I don't got that kind of money and detest modern vehicles with their snitching electronics), they feel a lot more solidly put together than the nissan leaf, for whatever that's worth. I don't have any special insight on the longevity, but short of a major electrical component failing prematurely, or another battery recall type issue with individual cells, the longevity will mostly be down to how it's been driven and charged.
My 2013 volt is an absolute tank. I had to replace a cell at 100k miles. I bought it at 60k and besides that have only had to change the oil and put new tires on it. The GM electric drive train seems really well designed, unless ofc it was enshittified.
the volt and the bolt are pretty different ofc but yeah. GM is seemingly fully capable of making a decent electric drivetrain, and besides the battery cell recalls and general software bullshit I haven't heard anything bad about the Bolt yet
Hear ya about modern vehicles. Waiting for the day they require an account to turn the radio on. Thanks for the word.
