It's not normal in the UK to ever touch another car with your own. However I have heard that it happens in some towns/cities on the continent. I'm guessing they park on flat roads and leave the handbrake off. No idea how a car is supposed to escape if it's wedged between two others though. As for dashcams, don't these normally switch off while the car is parked?
