I'm leary about using valet parking. But if I ever 'have to', I've got a car camera that shoots not only the street, but also the interior of the car AND records the cabin audio. It's a bit of a pain to review ~ you have to pop the simm card in a computer for viewing. I figure I''ll check the car for damage, etc. If any problems, I''ll pop out the simm card (it records on a loop - I don't want to record over the evidence), and go from there. Now that I think about it, I could put a spare simm card in the glove box . In case of an accident, or if I'm 'just not sure about that valet guy', I could put the evidence-simm in my wallet after anything at all suspicious, for later review, and pop a fresh one in the camera for the trip home. It also displays GPS route and mpg, although I doubt those will collect data in a parking garage.
