Nah, it is a matter of weight. Roads are engineered specifically for the weight of these trucks. If these trucks are regulated stupidly, the cost of goods goes up very quickly, the cost of road infrastructure skyrockets, or both. Making cars obese to protect the dumbest humans is one thing, but the constraints are different here. A commercial driver’s license is supposed to be a real license with real qualifications. That is your only protection. In a society where driving is required, the regular license is a joke with superficial qualifications. It is just a tax on the populous.
