Travelling north on the A21 to home I was filtering on the right of two lanes of stationary traffic due to red lights. Lights turned green and traffic started moving. Suddenly I saw a van on my left turning right. I shouted out but he managed to clip me knocking me to the ground.
Don't you think that this was a forseeable outcome of passing to the right of queueing traffic at a junction?
Whether indicating or not, any vehicle in lane 2 may well turn right at the junction and I would be very careful indeed with filtering where I couldn't be sure of reaching my ASL before the lights go green. If I can't be certain of reaching the ASL I'll look for a space to slot into within either lane. I'd never put myself to the side (either one) of any vehicle where it may turn into another road, it's just not worth the risk of being side-swiped.
I am not defending the police driver who certainly ought to have checked his mirror prior to turning but, given how squishy we are, we need to be anticipating the possible manoeuvres of drivers.
Glad you weren't seriously hurt and the bike's okay.
