Hi, When driving in the busy traffic i have always noticed this happening several times in the past .. There is a goods tempo or goods rickshaw or some sort of slow moving vehicle in the front and behind lot of vehicles standing in the signal. As soon as the signal goes green there is a loud noise everywhere from behind and in front the rickshaw is slowly starting up and crawling to cross the signal without leaving way to the traffic. It almost losing up crossing the signal and stopping at the same place the only the tempo would have passed the signal. Sometimes in mirror its shocking to see vehicles almost touching my car or some sort of pushing vandalism happening. how to handle this..
