Just musing after someone went into the back of me this afternoon, wondering what the norm is (I'm in the UK) and thought I'd do a Mumsnet dip sample.
I've been driving 18 years and have had someone go into the back of me 3 times. It's always been when I've been stationary (traffic, roundabout...) brake lights on but I've been driving different car makes and colours, all no fault obviously. It seems like quite a lot! I've also come back to my car in a car park to find someone has driven into it and caused damage.
Other than minor bumps when parking at home (catching fence etc)and that one time I clipped a farm animal I've not been the fault party.
