And if the lorry/large vehicle comes from behind?
At the end of the day, the lorry driver will be convicted but it will not bring back the dead cyclist. If we can make our fellow cyclist aware and avoid them being placed in that situation we will save lives. I have seen safety conscious cyclists get off their bike when a lorry comes from behind and Is just too close for comfort. I have done the same.
Pointless being a dead hero thinking that you were right as the lights go off in your life.
