There are plenty of laws regarding bumper height on lifted vehicles, it is generally the primary requirement, least here in MA, also with headlight heights too. I know many semi trucks that can easily roll over a car or even a pickup truck, also know of trucks that have done said thing. When a 80,000lb+ truck is rolling up behind you I would much rather make the safer choice and be in a vehicle with some mass and some height.Semis don't have bumpers at head level ... Nor do smart cars ...
If the rule applies to manufacturered vehicles, it should also apply to customized vehicles.
With your reasoning it could go the same way too and make lowered vehicles have bumper regulations too. I know plenty of factory cars whose bumpers would go right under my factory bumpers, never mind if I were to get rear ended, some SUV's will go under my truck at factory height.
Why does the big guy always get picked on for the sake of the little guy, I personally don't feel safe in any of these tiny cars they produce nowadays, and I am not talking about smart cars, I mean cavaliers, aveo's, focus, civics, ect and I personally won't buy one primarily for that reason.
