You say a Smart Car is too small for you? Shaq fits!

Talking about not wanting to get hit with a big truck or SUV in a Smart car... the structure of those cars is designed like a very rigid and strong cage, opposite of larger "normal" cars which have crumple zones and spaces meant to absorb impacts. A Smart car (or any tiny micro-car for that matter) is basically designed to smash into another car like a bowling ball and put all the impact energy into the other car. At worst a smart car might fly and bounce around in a crash but the passenger compartment won't get crushed.

Just don't run into any brick walls or freight trains lol. Or a 1950-70s Chrysler C-body or Imperial heh heh...
