Not to detract from the idea that trucks are dangerous (they most definitely are) but I’m not sure this is the best argument for this. An asshole in a truck doesn’t mean they necessarily will drive their truck down the sidewalk like what is common with assholes on two wheels. 4 wheels will do many other dangerous things. but assholes who ride their two wheels on sidewalks going top speed even at 15 without making room for pedestrians is a valid concern.
