We've had one car through our front wall, but there have been several accidents on the junction where we live, some due to excessive speed. It's a quietish suburban location, and looks as if nothing would ever happen here. The neighbour across the estate road has also had his wall demolished by a van.
I do have a High Vis winter jacket from work, which has blue lower arms, and on the odd occasion I've worn it on holiday, it has a noticeable effect on drivers.
