Today I was involved in a one vehicle accident when I scraped the side of the car while reversing into my lock-up garage. The problem was a vehicle parked directly opposite causing me to adopt an unusually tight curvature.
Leaving aside legal arguments about causation, could there be a technological solution? I wondered about a laser beam that if interrupted would sound an alarm, or a camera and screen or even a mirror.
I don't think a pressure pad connected to an alarm would work as the overhang is more the issue than the position of the wheel.
