>But we've got bigger worries with degraded batteries leading to e-waste, with Chevrolet discontinuing support for a 5yr-old EV (Chevy Spark) setting an example that others seem likely to follow.
The Spark is one EV from one manufacturer, introduced ten years ago, and it sold a few thousand units over a couple years. Chevy sells more Bolts in two months than the entire several year long Spark production.
The reason they're no longer selling battery packs is because there was insufficient demand for them. The car sold like shit. It is not "an example others seem likely to follow" like you claim.
Chevy included, given they're warrantying failed Bolt EV batteries and giving them 8 year warranties. Five year old bolts are getting eight-year-warrantied batteries. Weird you didn't cite that.
People have been bleating about "battery-pocalypse" - batteries clogging landfills, failing batteries "totaling" cars, blah blah - since the Prius came out twenty years ago. Still hasn't happened. If you have a Prius and the battery pack throws an error code, there are plenty of businesses offering rebuild services, looks like it's about $1k. They recycle whatever cells are still good, and bad cells are sent out to be recycled for their raw materials.
You either intentionally zeroed in on extreme outside case to push your anti-EV agenda, or you don't know much about hybrids/PHEVs/EVs and you're outside your lane while pushing an anti-EV agenda.
Which is it?
