Honda is testing this piece of technology in Indonesia, one of the busiest streets you can find in ASEAN.
This app changes color depending on the driving pattern of other drivers surrounding them. this will in turn tell if this kind of pattern will create traffic congestion.
I am still trying to digest how this will eventually help to relieve traffic congestion, as i feel that this app would be able to help reduce accidents instead of traffic jam. e.g. if i know this guy in front of me is always doing hard braking, then i should be aware to stay far away from him, just my 2 cents though.
