It uses a combination of Bluetooth (if you're near/connected to your car's stereo), motion sensor and GPS.

If you started moving at 70KM/h nowhere near a train or bus station, and then suddenly stopped moving at that speed and shortly after started moving at 5KM/h, you've clearly just got out of your car. Use bluetooth for extra verification if possible. When certain, get location (or load location) from GPS and mark spot. Tadaa, no fancy learning model needed.

Those sound like features that would be perfect for a learning model, otherwise you're stuck hardcoding the conditions and thresholds, no?

edit: anyway, besides the point.. I just love that feature haha

Yeah didn't mean to sound that abrasive.. damn booze.

It is a nice feature indeed

Acutally not neccessarily. You can as well end up in a traffic jam. In fact that's how they display traffic info on maps: many phone users doing what you just described.
