i agree, and im not trying to undermine modern research and development on emissions, but my point is that perhaps larger cars should be discouraged as they are hugely overkill for most people's needs and exist as status symbols - if coming purely from an emissions standpoint they are terrible compared to an equivalent small car or motorbike etc yet people seem to blame 2 strokes and old cars when in reality they are not the sole cause of the problem

Ah, yeah, that's fair. Each individual vintage vehicle is terrible, but there really aren't that many of them, whereas there are millions of large cars/pickups being sold per year. I'd certainly support some sort of measure aimed at large vehicles which aren't used for some sort of large-vehicle-appropriate task.

Slap up some rolling truck scales on your existing toll roads and pro-rate tolls with the discount maxing out right at GVWR (which you got by looking up their vehicle with your existing ALPRs) and then spend a decade hammering out edge cases.

It will never fly because the demographics that are usually supportive of that kind of legislative action are almost exactly the same demographics who buy 3-row SUVs for 2-kid households and hand wring like it's the end of the world if you put four adults in a compact car or throw plywood on a roof (but a kayak is fine).

Yes I mean classic cars are dirty but there are very few of them, most being used only seldom. However there are 10s of millions of >2 ton hunks of metal being used to haul mostly 1 person around, with all the consequences that implies: pollution, noise, space for roads, space for parking, traffic fatalities, etc. That's a real problem.
