Since the Tesla is such a small car, I found myself in a parking lot watching someone back into me through the rear view window. I saw them backing into me and honked. Fortunately they hit my bumper at only 1 or 2 mph. With the fabulous bumper technology today, neither car had any damage at all – not even a tiny scratch. The biggest lesson is how invisible the Tesla can be to other drivers.
The Roadster was a bit dirty but not even the tiniest scratch.
