I've said it once, I'll say it again: I'm NOT into cars that are connected to the internet, and apparently bluetooth is about as bad. I don't want some 0-day meaning some hacker can disable my brake line when I'm barrelling down the highway at full speed, and I don't want someone hacking into my car in the parking lot. I don't like smart garage door openers for the same reason: Hackers can just walk in with the right exploit, with no trace when they leave.
