No. That would only be potentially true if people were proposing a law to limit the form factor of trucks that are driven in cities (and even if so, it would not be obvious; you'd have to look at the numbers). Since that isn't feasible, and all the proposed laws are about limiting the form factor of all consumer trucks, the average statics are the relevant ones.

You can always find a subpopulation where some effect is large; that can't be good reason to make rules that constrain the entire population.
