This is a true point, but it applies to SUV's as well as trucks. This is more an argument for moving to a sedan-dominated fleet than an argument against trucks... but good luck: in the USA, SUVs and trucks are two very hot market segments.
Cities should start taxing the size of vehicles too if they're going to let people park on the street. Smart cars are a fantastic utility vehicle for example, but are not incentivised enough.
