‘They really shouldn’t let those small cars drive in traffic. I worry I’m going to kill someone if I hit one! They should have to drive on the sidewalk, safely out of the way.’

in reality most (all?) states in the US don’t charge progressively more for vehicle registration based on weight, and even when they do, the thresholds are really high. So a F-150 weighing over 5000 lbs may pay the same as a Honda Civic weighing half of that.
Right but the comment you’re replying to is talking about sticker price and gas, not registration.
the original (my) comment mentions tax
Which they already pay, the sales tax would be higher and they’re paying more in gas taxes.
and yet, people keep buying these things to buy groceries and drive on asphalt, so just fuel inefficiency is clearly not enough
Yeah, but I’m with the OP here. It should cost significantly more tax wise than it does to disincentivize it
Texas used to, maybe still does. You made me try to look it up and couldn’t find a simple source. Plenty of states use MRSP or some measure of the vehicle’s value.
Back in the day (Tulsa, OK) my friend had a 2-ton dump truck with antique tags (over 25-yo), paid $20. Meanwhile, someone buying a super-light Corvette was paying $650. (early 90s money)
I say go on weight, maybe some factoring of value. Registration fees are paying for roads, if your monster vehicle is doing more damage, you pay more.
Fuel taxes are paying for roads.
Subsidies are paying for roads.
The F350 is the smallest vehicle where they charge by weight. Unfortunately they don’t check for how much you use it, so for the 6 times a year I use mine I’m paying $.10/mile - while someone else who uses it for hauling as a job is paying $.01/mile.
That’s your state. Just looked and registration fees and tags are all over the place.
True, but as a general rule until you get to the F350 class or higher states don’t charge that extra tax.
