I think they tried that but he checked the exit route behind his car as he got into and was looking out the rear window and the mirrors (for his hedge one side and the fence the other) as one does when reversing?
But yes, if there was someone or something *under* the back of most peoples cars as they back out of their own drives, I'm guessing most people would have the same result, especially if they approached it from the front (or from the back if they had reversed in)?
The same applies to those who back into short posts in car parks or scrape them down the side because they are below their line_of_sight and under the mirror?
They muttered and mumbled a bit but didn't do anything, other than extract their slightly worse-for-wear box from his drive and went away.
