Agreed. I do not administer such an exam.

Instead, I find myself saying things like:

1. "You know your engine light is on, right ?" ... "Yeah, its been doing that."

2. "Whats that noise coming from the front wheel hub ?" ... "I dunno."

3. etc.

You get the idea. One groups vehicles are absolutely better maintained, and quantitatively safer to ride in or drive, and its within my perception, so the 3rd degree interogation is pointless.
