You're saying there are an equal number of cars as trucks?
Truck's speeds should be regulated by requiring them to have the same stopping distance as a car.
The rate of death caused by cars is really, really close to the rate of death caused by big trucks (about 1.1 deaths per 100 million miles driven)
There is not much difference in the safety of trucks vs. cars as far as the death rate. Of course, the trucks are almost always driven by legally licensed non-drunks whereas the cars are often driven by drunken, drugged up idiots. So, if you had only reasonable people behind the wheel, the trucks would be more deadly.
Truck drivers are currently hyper regulated.
Regulation causes many accidents. Regulation’s prime purpose is to make big trucking companies bigger. Regulation is not safety.
