Repeal CAFE standards, or just delete the entire catagory of “light truck”. If it doesn’t have a bed, its not a fucking truck. This entire fucked situation is literally just automakers not wanting to be bothered to make fuel efficient cars when you can call everything a fucking truck and be mostly exempt from having to comply with the far stricter regulations around smaller passenger vehicles MPG standards.
And the automakers give zero shits since they make so much more selling these larger utterly pointless vehicles rather than smaller, more economical ones.
