One time I hit another car
which was in front of me, it was a strong push, but that car had the pipe to block it, so it did not damage the car, and they only told me to be careful, then let me go.
Some other people hit my car twice, and it is only a small bumper, my car is a 2000 toyota corolla, I do not car, just let them go.
If it is not big problem, just let them go, make life easy for you and for other people.
