"Accident" is an ambiguous term and should be banned from any discussion of vehicle collisions. The key element is whether the driver was negligent. Could the death have been prevented by the actions of a reasonable driver. Unfortunately, society has not come to an agreement on what constitutes reasonable driving behavior.
Not really into the banning of words....
The key element is not whether the driver was negligent, but whether the driver and/or the cyclist was negligent. Being a cyclist is not a guarantee of innocence.
