Stuff like this has been around forever. I once drove a 2007 BMW 7 series which let me unlock/lock my car from my phone. I also got weather data etc. on my dash.

Now it is finally making it to normal cars. My 2014 Passat has it as well. However, I didn't activate it since it is tracking my location.

On the other hand, stuff like Onstar can save lives.
