Let's say that there's a superpowered character who has superstrength, control, speed, and durability, but no super friction powers.
Ordinarily he can only accelerate about as fast as a motorbike although he has a lot more power in theory. One day he needs to go a lot faster, so he steps up the power to the extent where instead of running through friction, he aims to run through thrust, by overcoming the material strength of the ground and pushing his foot through the ground so fast that he can propel it away from his foot at absurdly preposterous enough velocities to give his own body a fast speed kick forwards.
Now, the question is: shouldn't he actually spiral out of control because the thrust is occurring at his foot and not at his center of mass? What direction will he rotate in? Will he rotate away from the material he pushed exactly like if he had a rocket attached to his foot (that briefly fired), or will he rotate around his own leg due to torque?
