This could simply be avoided by introducing a similar model to how it is handled over here in europe, with different vehicle classes and weight limits, a higher weight class requires a more advanced drivers license. Certain utlilty vehicles 3.5t and over can't be driven here without a D class license, which costs extra, requires extra training and the tax and fee structure for these vehicles is drastically different.
Usually, these heavier vehicles also pay higher toll fees on toll roads like in France, Spain, Austria, Italy, etc.
In Austria higher engine power vehicles also cost more on a monthly basis, while registration is a 150€ one time fee, monthly insurance and tax can be around 150€ for a 200hp ice vehicle, even just a Ford Fiesta.
