Aaaahhhhh, gotta love that good ol fashioned paranoia    As somebody who wadded a motorbike up and was found in a field by a caltrans worker, I don't think I'd have to think twice about helping somebody after they crashed a motorbike, and having helped way more people than I'd like to remember when they crashed on rides with us, I never told somebody "I can't help you up the hill, but if you want to wait 10-20 minutes I'm sure the proper personell will be here to help!". 

It's sad when we live in such a fawked up society that people have to think twice before helping somebody out of harm's way
