I assume that in law a cyclist should take the same care as a motorist in respect of pedestrians, ie. to anticipate possible unexpected behaviour and to be extra cautious. I believe the cyclist saw the woman and called out or gave some sort of warning. But did he slow down? A cyclist can do quite a lot of damage, especially if pedalling fast.
In this case, on the face of it, it seems unfair that this young woman has been awarded over £4,000, and the cyclist has got to pay £100,000 in costs. Presumably, if the cyclist had negotiated a settlement with the woman, he could have avoided the legal fees. If he appointed a solicitor, he might have been better advised to repreent himself and to make an offer of settlement.- - but there would still be the issue of her fees.
If I were that woman, I would feel guilty to have had such a huge financial and emotional impact on this man's life. She should not have been looking at her phone. In law she had the right to pursue a claim but, ethically, I think it was wrong of her, especially as he was hurt too.
I don't suppose all cyclists think about getting themselves insured but perhaps this will scare them into doing so. I think I agree with suzie that it should be compulsory for cyclists to get insurance - for the sake of both parties.
