Control your car's steering and movement from an app with openpilot. Designed to be a gimmick feature more than anything. It's a mock Tesla Summon.
Download the app here.
This is now outdated and only works on openpilot 0.5.12 (branch release2) on Arne's fork here. Phantom also works on Arne's 066-clean branch, however it is not tested and VERY buggy.
