I once swapped a Bond Bug in bits for some electronic parts that I had lying around. I then started to restore it.I immediately stopped working on it as a result of the ride I'd had as a passenger in one. It is as dangerous a vehicle as a Sinclair C5 would be on the road, but for different reasons of course.
I am not averse to open cars, or speed, having built a 300bhp 700kg road legal sports/racing car, but it stops and corners(unlike the Bug), and is, unlike the C5, visible to other traffic, oh and it has a cage and harnesses in case of accident
