that too but the wheels specifically do some weird things over the bumps and during landing
eg in the second video at around 0:58 (where the 2 cars land side by side) if you look at it frame by frame theres a lot of weird crap happening that shouldnt be
on the car on the right at least one of the wheels even appears to switch position to the centreline of the car
and in the first video the wheels sink into the ground a lot
