What are positive_behavior_tags in the v2 Driver Performance Events?

The positive behavior tags are added to a particular driver, if it is observed that the driver was alert during the trip and was not involved in any misdemeanors such as hard_accel, hard_brake, hard_corner, crash, or others.

For such drivers, these tags are added and they are as follows:

alert_driving: This is an annotation tag that is added when a driver is observed to be mostly alert.
safe_distancing: This is a video tag that is added when it is observed that the driver has maintained a safe distance to other vehicles during a trip.
