Don't try to steal a Tesla. Or if you do, try and make off with the owner's smartphone too ;)

Tesla owner tracks stolen car with app, helps police arrest thief.

Note to car thieves: Don't try to steal a Tesla. Or if you do, try and make off with the owner's smartphone too. I mean, I'm not suggesting you steal any cars because that's illegal and generally a mean thing to do, but if you simply must steal, don't bother with a Tesla. 

A Vancouver Tesla owner whose car was stolen from an underground parking lot was able to track the theft in real-time, working with the local authorities to corner and arrest the thief, The Province reports.
After attending a concert, the owner, Katya Pinkowski, and a friend went to garage where the Tesla was originally parked, only to find that the car was no longer there. After a call to the local towing company revealed that no Tesla had been towed that night, Pinkowski called her husband, Cary Pinkowski, who pulled up the Tesla app on his phone.
There he found that the car was on the move, so he called the police, giving them real-time updates on the car's position. While the Pinkowskis considered having a bit of fun with the thief — the app lets you remotely honk the horn and open the sunroof — they decided the responsible thing to do would be to let the authorities coordinate an arrest. The police surrounded and arrested the thief, returning the Tesla to its owners later that night.
“It was so much fun, actually,” said Cary Pinkowski, speaking to The Province. The Richmond, B.C. police had never recovered a stolen Tesla before, and it was the first time they were able to track a car in real-time.
So, how was the Tesla stolen in the first place, then? The Pinkowskis purchased an additional remote key fob for their car, which they mistakenly left in the vehicle. As is the case with many modern cars, the doors are easily unlocked if the key fob is within proximity, hence why the Tesla thief was so able to easily make off with the car.
Vehicle tracking isn't unique to Tesla, either. Many other automakers — like Mercedes-Benz with its Mbrace app and GM with OnStar, for example — offer similar sort of stolen vehicle tracking, leveraging connected car tech against conniving car thieves.
It's a far cry from the days where stealing a car was as simple as popping the hood from the outside, forcing your way inside and hot-wiring it. Just, don't leave the key fob in the car.
