Car drive trains never work. Never. They always have a turning radius of some sort, often several feet, and there is never enough room on the field to make these kinds of manuevers. Can you imagine having to make a 3 point turn every time you wanted to turn around? Or you could easily get pushed sideways against the side of the field and keps there by a robot simply not letting you make a left turn to get pointed away from the border. They're simply not nimble enough to be very successful in FIRST competitions.
