1.The tank tracks do not appear to be taken into consideration when calculating the suspension, collision, and traction of the wheels, ie, the wheels will instantly snap to their maximum extension when they pass over a curb, wedging said curb between two wheels with the tracks phasing right through it instead of said track suspending the wheels and allowing a smooth transition over it. Also it just makes the whole thing jarringly bouncy.
- The tank loses its momentum too quickly and will not rev up when it thinks it is pressed against something thus the tracks cannot dig in and force its sloped front end to slide up the obstacle until its tracks can grip it themselves, which brings me to my final point.
- The tracks/wheels do not grip said obstacles and thus either do not rev at all when supported by it or experience no traction and thus spin uselessly against it. On the other hand the tank can spin and bounce on the obstacle just fine.
