How, exactly, does this work on cars that have no remote door locks or remote ignition?All cars are subject to it! From the most expensive to the cheapest!

Many cars were designed assuming only the legitimate car software has access to this network, so they don't provide any protection once the bad guys are there. Thus, once the bad guy can run arbitrary code on one of the systems connected to the CAN they can do things such as disabling the brakes, opening the throttle or, in more software-based cars even control the steering and more. And at the very least they could open the car remotely and start the ignition.
Tesla being originated from a guy that really gets software I can imagine some significant precautions have been taken, but I would really love to know how much attention has been paid to software security and how formally has this been addressed (there are well-defined and publicly available software security processes that should be followed by anyone developing commercial or critical software).
I would expect that no attention whatsoever has been paid to software security in the model S. We have heard of no evidence that Tesla has made any serious attempts to provide any security, and I know that most software development companies don't try very hard, especially when they're rushed.
It's a risk I'm willing to live with. But don't have any illusions about Tesla. If they had designed a secure system, they would have advertised the hell out of it. They didn't.
(Edit: to be clear, the other carmakers are just as insecure.)
