The car is the man's property as much as the parking lot is the company's. If my boss told me he wanted to search my car everyday and to forbid me to have this or that in it on the basis that he pays for the parking lot, I'd tell him to take a flying leap and find a new boss.

That is exactly my point. You have the right to work somewhere else if the terms and conditions of that job don't suit you, and your boss has the right to dictate what can be brought on to his property. You can't tell him how to use his property and he can't tell you where to work or what to do on your own time.
