so if the bike was a car .....

whose fault then ????

surely its down to the vehicle behind to be aware of whats going on in front of it ???

if you had dropped from 40 down to 10 then its fairly obvious that you were gong to do something .. and by his own admission he saw you slowing ..

how can an insurance co say its 50/50

if you have an accident by hittng someone from behind how you gonna say its half their fault for slowing down ???
