Let the hive mind of Engadget get that for you.
"We need a digital camera that can be switched on and fire off that first shot fast. It's not a commonly tracked statistic on any review site, and nobody seems to have this information for every camera. We were hoping other readers could inform us as to what small digital cameras can fire off their first pics in under a second (ideally under half a second). It needs to be small, but mostly, just really quick in operation. Thanks!"
I can see how the waxing issue would be a problem. I would imagine with something like this on the car, you wouldn't want to wax it at all. The wax will show and keep scratches, the paint will not.
There may be long term affects related to repainting / refinishing, but when there is new and better technology, people must adapt to it.
