>"in order to offer good driver incentives"
You can't determine if someone is a "good driver" from a phone. PERIOD. Speed, G-forces, where you are driving, when you are driving, NONE OF THAT determines if you are
1) Leaving reasonable following distance
2) In control
3) Alert and paying attention
4) Using proper signaling
6) Familiar with the limits of function of the vehicle
etc. They seem to think that if you brake hard, accelerate faster than some "typical norm", or corner too hard, you are a bad driver... and that simply is neither true nor fair.
