I knocked a lady off her bike last week after pulling out from a side street. It was dusk and I didn't see her at all despite looking. Luckily she was unhurt (although obviously shaken) and her bike was undamaged too. I only saw her when she went in-front of the headlights and managed to slam full on (had only just set off so wasn't going very fast) and just clipped her, causing her to skid sideways.
She was dressed in very dark colours and her light was quite frankly crap, but it made me wonder if I'd really looked? (as I suppose I tend to drive automatically a lot of the time). Decided I need to make more of an effort to look in future.
It shit me up at the time, after checking she was OK I gave her a lift to her destination to make sure she was OK, with her bike in the back..so no damage done in the end thankfully.
