Dave,
I am unsure as to what you are an "expert" in, are you saying that you drive a "clapped out" old bus , if so I am surprised that such an expert would even contemplate driving a "wreck"
If, in your expert opinion, the vehicle you drive is unroadworthy, then you are aware of your responsibilities to yourself and to the public, you don't need any advise from a fellow expert.
Anyway-have a nice day
