17、helf out of reach,a patch of ice on the misfortunefrustration,tiredness or just bad temperthat show what the accident really is,a sort of attack on oneself.

18、ves and the world that they seem to cause accidents for themselves and others. By definition,an accident is something you can not predict or avoid,and the idea which used to be current, that the majority of road accidents are caused by a minority of criminally careless drivers,is not supported by in
