I tried it once. Installed the app on my phone. The error rate in the data they collected was ridiculously high. Get a phone call while driving? Welp, now it says you were on the phone for 45 seconds. Playing music through the stereo? No, you were clearly using your phone the entire time. Phone slides around on the console? You clearly must have mashed the brakes.

I decided that the best way for them to determine I was a safe driver was the fact that I haven't had an accident claim in years.
