If you don't feel like you're giving off enough of a James Bond vibe—and happen to own a 2011 Cadillac or Chevy—OnStar's new MyLink apps might help. And they're useful! Unlock doors, check gas levels—even start the ignition.
An active OnStar subscription will be required, and previous auto models won't be eligible, but it looks like some pretty neat (and reassuring) functionality on your iPhone or Android. But if you've got the necessary gear, you'll have access to oil levels, lifetime MPG, tire pressure, and battery charge level, for Volt drivers (along with many other stats). It won't let you drive the thing using the accelerometer, but, hey, baby steps. [iTunes via TheNextWeb]
