After reading a few post about various methods of stopping cars. I thought I would show off my "Stop Box" and see what the collective thinks. I know some have stated that abrupt stops can damage cars,...but what kind of damage? So far this has worked well for me, and it keeps the cars from slamming into each other, chipping paint, scratches etc. Let me know what you think. O yeah, show everyone what you are using, with pictures to give us a better idea.
