We now have two cars with no ignition key. One has absolutely no key at all, just a push button start and the other you can use the key in an emergency. I hate it as I'm constantly worried about losing the key(s), with a keyed ignition it's almost impossible to lose it while your in the car as it's obvious where you have to put it.
This is not an advancement imo it's a pain in the arse, what say you ?
