So sorry about your car.
I think if I was a regular user of this Supercharger I would do three things:
1. Use the last open slot on the left side.
2. Back as far as possible to give the most room in front of the car.
3. Build a device to protect the front of my car.
I was thinking of something that I can roll up for storage, then unroll and attach to the front, kind of like a protective blanket. It would have two walls, the inside against the car would be soft with foam padding. The outside layer would have some sort of "crumple zone" but the outside would be highly reflective, with something like 4 inch nails sticking out. If anyone got too close the nails would warn them they are too close as the side of their car or truck was scratched. It would have to be tall enough that any side mirrors would get the warning first. I may even have flashing warning lights on it.
Since only the right front would be exposed when parked on the left side, or the left front exposed when parked on the right, this device would not have to be too long, maybe 4 feet tall, and maybe 2 feet across. Maybe 4 inches of crumple zone, plus the 4 inch nails, would only take up about 8 inches of space so it would be the same as stopping 8 inches from the very back of the parking stall.
Now that I am thinking about it, I could see the outside being two pieces of 1/4" plywood with heavy cloth or old carpet as the hinge. This way you could pound the nails, or even deck screws, from the inside out. It could all be spray painted with some bright reflective paint as warning, with small, battery operated flashing lights that could be switched on when charging to give further warning to cars passing by.
Maybe a couple of these could be built and left at the Supercharger, one for the first car on each side to use. Maybe we do not have to attached them to the car, but drill a mounting hole in the concrete floor at the proper distance from where the car should be, then just attached it to the floor when you set it up after parking. That sounds better so when it is hit it will not push against the car.
any thoughts????
