My 2001 Landcruiser with over 1,000,000 kms on the clock had a solid front axle and never did anything like a death wobble. For that matter, nor did our ‘96 Jeep Grand Cherokee. Maybe the longer wheelbase helped
the size doesnt matter for aerodynamics, generally, but it matters for physics.
Drag is a square or cube scaling, i forget which, so at higher speeds it increases disproportionately.
A larger object has more air to move out of the way, which means more drag. It's more capable of moving that air with it's increased volume. But then you also start running into volume to surface area scaling issues. Elephants are really slow for a reason, and it's the same reason small animals are comparatively fast.
I'm thinking entirely too hard for a meme about the aerodynamics of a pokemon, but there's no way that a literal Bulbasaur can beat an actual car, right?
