Respect is not the word to be used here. Respect is reserved for people who fought for our country in war for example, or for surgeons who spend their working days saving lives, or possibly even for the postman who manages to deliver the mail on foot when there's 12" of snow on the ground. Respect is not what I would feel for any person breaking the law and dying as a result.
I don't respect politicians who abuse their powers and claim expenses fraudulently, nor do I respect the police who find it necessary to manufacture evidence to convict people who are innocent of the crime they are charged with, or the slimy git who thought it reasonable to put a deep scratch down the side of my last car for no apparent reason.
Respect is something to be given when deserved. In what way does the bike rider gain or earn respect? I feel sorry for his mother, and for the driver of the car who survived and has to live with the consequence of his / her actions, and also for the biker. But I can't find any respect anywhere for any of them, save perhaps his mother who is doing the most noble thing she can to try and make sure no one else has to go through the same thing.
