Just to clarify, he asked for a downside of trucks, I said they're far more likely to kill pedestrians and bikers than normal-sized cars in the event the driver hits someone (which is true). And the next logical step is "we should all live in the farmland and not leave the house at night"?
I think there's a difference between "One drawback is higher pedestrian fatality rates" and "They're basically custom-designed to kill pedestrians and bikers".
