An interesting discussion. For my Euros worth, the car driver was wrong not to have seen the bike and other vehicle, or, at least, not to have reacted in a proper way. The motorcyclist did not cause the accident, but severely reduced his chances of avoiding the accident, let alone surviving it .... there are plenty of bits of road where you can open up the throttle and do 160+ mph if you have a mind to, which are quite safe from all but leaping deer and pheasants etc ..... this road junction was not one of them .... 97 mph gave this poor young man no chance .... and even if the car driver did see him, he may well have pulled out, anyway..
