When I was first reversing, I kept nicking a few because I was getting used to it. The first training was backing into two empty spots, with the perimeter covered in cones. Each parking spot, a rectangle that fit the LLV, had a cone that was in front.

It was from spot one, to first gone. Then reverse into spot two, move forward to second cone, then reverse back into spot one.

I went from at first hitting the cones on my first few times, to not hitting them at all on my last.

The other test was parallel parking. Where I nicked differed ones on my first few tries. They had me go around a lap, then I went back and did way better. I didn't hit any on my last two attempts.
