New Mazdas become hacker’s delight?

It looks like Mazda has released a concept car that will be using a USB key instead of the usual cylinder keys. While this sounds like geeky gadget porn, I can’t help be wonder how useful this could be. I love my gadgets, but I’m not about to start my car with a USB keydrive, not to mention it would be easier than pie to hack and steal people’s cars. What were you thinking, Mazda? Oh, sorry. I’m sure a brilliant manager thought up this brilliant scheme.
