Trucks are commercial vehicles. People driving commercial vehicles should be professionals and we should have required a commercial class c license for all light duty pickup trucks or SUVs. Anything that gets an emissions credit so they can have lower MPG for being a commercial vehicle should also be classed as a commercial vehicle for licensing purposes.

Trucks in America practically doubled in size within the last couple years. Expecting everything to change that quickly is ridiculous. If big trucks stick around then sure, expect infrastructure to become rated for it and also more expensive.

Trucks are driven by people that are supposed to be way better than the average driver. They also would need huge (and expensive) walls. At some point you have to compromise. It's not feasible to truck-proof the roads.

I don't think there's a way to make it work for both cases.

It's actually important that the rail gives in and deforms, as this reduces a cars energy much more quickly and safely than if it were rigid. Unfortunately this also makes them much less effective for larger vehicles.

In the end, it's a question of protecting as many people as well as possible.

At the moment I believe there are minority that's becoming a majority but I maintain that if they're the ones that require the infrastructure the payment for that infrastructure should be built into the cost of the vehicle or the licensure thereof.
