I am really good at parking so I don't use IPA all that much. The only time I use it is to test it to make sure that it works so when I show it to people, it won't park all crooked. The only IPA feature I test regularly is the backing in. I've only tested the parallel parking once. The end result was that it parked 2 feet away from the curb. I was afraid of it curbing the 17" wheel which is expensive to replace and hard to find. Can the IPA curb the rims? Can it turn too early and damage the front bumper by hitting the car in front of me? I know it has the sensors on the bumper but when I did the parallel parking, it looked like it's going to hit the car in front of me.
