They were able to successfully get root access to the car's system (not chroot, real full root access) and with that they were able to fully access to the car's API within Tesla OS. They even showed a video about one of the guys driving the car at low speed and the other one remotely accessing to the car's Linux shell by SSH and shutting down the whole car while the first guy was riding.
The interesting thing is that for higher speeds, for example more than 50 km/h, the car seems to override any of the Linux systems and the root access becomes useless, it stops working.
In another words, the car is able to decouple itself from the Tesla OS.

I cringe from the PR implications as I say this but really I fully supported Jeb! when he shrugged about one of the shootings. If we want freedom, we will have some missteps. I kind of wish we could say the same about religious extremists but that ship was always under command of the same bigots who controlled the conversation during the red scare.
For example: Remote door unlock command issued by the mobile phone app will not work if the car is moving.
