Society generally accepts small, fast sports cars and slow, heavy trucks, but fast, heavy trucks are something new. Sports cars are accepted I think in part because they're not designed like battering rams. If a sports car is in a wreck it'll probably take severe damage, and the driver is at a pretty high risk of injury too even if the car has sophisticated safety features. With this new Hummer, someone could sneeze and plow through three lanes of traffic and come out unscathed. The consequences of risky behavior are falling disproportionatly on the people who don't drive big trucks.
(This argument applies also to EVs like the Model S to a somewhat lesser degree. They're also fast and heavy, but they at least don't look like something you'd smash through a roadblock in some action movie with, so they kind of get a free pass.)
Requiring a CDL for certain vehicles that are heavier, more powerful, and with high risk of damage or injury to others seems like a reasonable option to me.
Why only them? The basic driver test is a joke. They should make the testing more strict for everyone. The license requirements for a CDL are probably more strict than you think (health, alcohol, etc).
Then you have things like one must be 21 to cross state lines, and 18 to get a learner's permit. Some criminal history, like felonies, will prevent you from getting a license.
So it's a bit more than not being on the verge of a diabetic coma. And if those restrictions are a good idea for personal vehicles, then why not do that for everyone?
Driving and texting in a full size car or a crossover isn’t any less dangerous to pedestrians than texting and driving in a truck. Full blackouts (the effect of driving and texting) means full speed hits and reduced visibility is irrelevant.
technically yes, but the effect of more mass in a vehicle-pedestrian collision is asymptotic. a small (3000 lbs) sedan is already 15-20x the mass of a typical human. the vehicle loses a very small fraction of its initial velocity to momentum transfer. it really doesn't make much difference if you double or triple the mass of the vehicle.
try playing around with a momentum calculator to see what I mean: https://www.omnicalculator.com/physics/conservation-of-momen...
