It’s getting really dangerous to drive what used to be a normal sized vehicle on the roads today. People shouldn’t be able to privately purchase 7,000lb+ vehicles for road use.
People shouldn't be able to drive a huge RV without a special license just because it's a RV, but that's a whole other topic.
I contend that people shouldn't be able to tow much behind a vehicle without a license endorsement. When I was 17, my car broke down driving between schools. Got a ride home, hooked up the 24' enclosed trailer to the truck, unloaded the race car and set off to pick up the car. Everything I did was 100% legal and it shouldn't have been.
I think the bigger concern than a vehicles weight is the amount of distracted driving that occurs. I see it every day and it doesn't matter what they are driving, subcompact all the way up to OTR drivers.
