Good for those endless streams of sentimental emails your buddies annoy you with, but totally fake.
How do I know?
1: If he loved her, why was HE the only one wearing a helmet in the first place?
2: Virtually every motorcycle has independent front and rear brakes.. if one went out you have the other.. not to mention that a couple throttle-less downshift would help slow the bike quite a bit.
3: If he thought he was about to crash, he wouldn't have time to get her to put on the helmet.
4: Have you ever ridden a bike at 100mph? Even with a helmet talking to the passenger would be extremely difficult... if she wasn't wearing one it is downright impossible... wind noise over your head at that speed is just a roar.. she wouldn't have been able to hear him is he was screaming at the top of his lungs.
If you don't believe me stick your head out the window of your car at 100mph and see if you can hear your front seat passenger... on second thought, DON'T.. I don't want you to be decapitated by a road sign or something.
