This may be anecdotal but worthy of an entry. Colleagues at the Bar report an increase in prosecutions of motorists causing accidents involving cyclists. Therefore, be careful when opening doors and that goes for passengers too. And, please remind yourself of the obvious, visibility is reduced in inclement weather. On the other side of the coin, cyclists who disobey the Highway Code, contribute to the incidents involving injury.
Ultimately, it always comes down to two things – in too much of a hurry, or not paying attention. Please be careful out there, that cyclist could be me!
