Alert: Excessive traffic deceleration.
Irrespective of cause, unusually great deceleration of one vehicle is a hazard for the vehicles behind - at least on highways with average speed above that of city traffic.
Real-time alerts from the Waze system via our community of users may offer a unique opportunity to prevent (or reduce injuries and damage of) highway mass crashes.
Various alerting criteria may be used e.g:
Client accelerometers (or GPS-speed time derivatives) indicating a deceleration greater than, say, the 80th percentile for that road (segment) or average speed level - established by Waze server statistics.
Traffic color ought be logarithmic with respect to MY speed, as fixed limits are useless in every sense
speeding is RARELY reckless commented

I've heard that telematics are noticing that the number of sudden decelerations per 100 miles is a significant indicator of a driver's accident risk. Tracking this number would be very useful, and would help us get to our destinations better by being more likely to arrive alive!
