Could we please stop this hands-free-everywhere nonsense ?
Convenience is a good thing, but not when it is tied to a platform as insecure as a mobile phone.
Oh well, I know I'm pissing in the wind, so I'll just wait for the inevitable massive phone hacks followed by a rash of stolen cars with insurances refusing to pay because car was not locked. That's when people will get the pitchforks out and cry about how they didn't know. Then they'll have learned a lesson.
Until next time, that is.
