The engineers of my team told me that we can turn in place by just turning the steering wheels almost perpedicular to the front and spinning the front wheels in opposite directions(ie- to turn left in place, spin the left wheel backwards and the right wheel forward). I am sceptical of this method. Will it really work?
It's more complex mechanically, and the software will be a pain, but once dialed-in, it should work fairly well.

Do you think it would be possible to determine the angle of the rack based on this information, and the distance?
It will be hard to do this because you have too few pixels to work with. As an example, from the closest starting distance possible (~180 inches), the light at 0 degrees only lights-up 12 pixels, at 25 degrees 8 pixels are illuminated. I think you're better off with a scoring mechanism that will work over greater range of angles.
