Flawed analogy I'm afraid. I see some value from having locks on my car, they are there for my direct benefit as per locks on the front door of my house. DRM only benefits the publisher, while the customer only gets inconvenienced by DRM'd products. It doesn't stop the pirates and they don't have to worry about DRM restrictions as they have been removed/bypassed on the pirated version. There is an interesting article that covers this very point here:

Would you buy a car knowing that at any time the dealer could simply stop you using the product without you having any recourse, that you might not be able to sell it second hand or that if the dealer went bust you wouldn't be able to use the car any more? That sounds more like a hire car to me, in which case I'd expect to be paying hire car prices. That is effectively what DRM is, the renting of software, and it should be priced accordingly.
The music industry have recently adopted a new model where, for a fixed fee each month, you can have access to millions of songs but they are DRM'd. If the games industry could agreed and charge a reasonable monthly fee, then I'd be happy to 'rent' the latest games and then just buy the ones I really liked for future use without any DRM (eg iTunes are now offering DRM free songs for a slightly higher fee).
One compromise, as I have suggested before, would be for a publisher to promise to remove all DRM after a set period (say 6-12 months) once the main sales have been achieved.
