just after some pointers really, all the tutorials seem to be about training your car to navigate a track, which i can do, however they never seem to cope with being stuck against a wall (say, after an impact knocks them off course). by putting complex obstacles patterns in the way for training, they just learn to avoid them as expected. am i asking too much of it? what would the the normal way to deal with such things? switch models when detecting we are stuck for one that's trained to get out away from a wall, and then switch back again?
