Personally, I'm not particularly enthused about what an apple car might turn out to be, but when you have $150 billion burning a hole in your pocket, you'd be crazy not to try. My biggest concern about this whole thing is that Apple's lawyers are working overtime filing patent applications and will shortly be going on the warpath against the entire auto industry.

I'm also not excited about the prospects for what the designer of the Ford 021c will produce http://en.wikipedia.org/wiki/Ford_021C?

Last year, when my daughter moved into her house, I put +Kwikset SmartKey door locks on for her. This week she decided she wanted to re-key and the whole job took less than a minute and only cost $10 each. With these locks, you put in the old key, turn 90 degrees, insert the special tool, pull out the old key, insert the new key and turn back. That's it, the lock is reprogrammed to the new key. The kit comes with 4 main keys plus 2 alternates. 

If you have someone coming in to do some work, you can quickly reprogram the lock to the alternate key, give it to someone one and when the job is done, you switch back to the original key.?
