Trying to ban them would be extraordinarily difficult. A potential solution would be to push to reclassify them as trucks, under trucking regulations (I'm unsure how this is done in the US). Once you need a tachograph and a requirement to keep driving records, it would cut back on sales. It also still allows "legitimate" usage. This would weaken the argument against the change.
Basically anything where you can't see a 5 year old within 0.5m of your bumper should be under "truck" rules, not "car" rules.
