I'd much rather see this handled through safety regulations than through additional incentives! NHTSA (and EPA, for that matter) has the authority to start shrinking car size - what it needs is political support, cultural will, and administrative capacity

You'd have to undo decades of policymaking that has made it clear the US government thinks vehicle lightweighting is bad and dangerous

Yeah, I’m sure NHTSA, one of the most regulatory captured agencies in the country, which has consistently failed to hold even Tesla to account, will get right on that. Fuck man, we have to depend on IIHS to crash test cars and make them safer because NHTSA sucks ass.
