I like the idea of just having a tax linked directly to how much wear a vehicle causes to roads, because the wear goes up exponentially with weight. Not only would this make oversized cars (and cars in general) much more expensive, it would also provide the funds needed to repair roads that get completely annihilated by trucking companies.

the average carpayment is 750 new, 500 used. I bought a new car last year and my payment is $300. technically i could afford like a $1000 payment.

americans often pay like 30%+ of their income to cars. And yes, they actively choose to do this. Nobody is forcing them to buy a 60K F150 over a 30K sedan.
