Driving — Rash driving by driver by sudden switching lanes posing life threatening danger to me in bike following it

Address:

kolkata kestopur

This is to report to the concerned authority against a rash car driving case near MG METRO KOLKATA at around 3:20pm. car no. WB12D5812. I was in a bike with my wife following the car in the nxt right lane. since it is a busy road, the distance was not that much between the car and my bike. And all of a sudden, out of nowhere, the car driver switches the lane to right. It was by God's grace that i somehow managed to control my bike which was in speed range 30-40kmph, or otherwise a fatal accident could have happened to us.
After that, we stopped the car and to our surprise, instead of apologies, the driver started shouting at us. The lady sitting behind, who seemed to be the car owner, who had no idea of the issue started blaming us (no idea why) and started defending her driver.
This is a very serious case of rash driving in a metro like kolkata where drivers and car owners think they own the city of they own an expensive car and starts arguments which are baseless. We just averted a major accident which could have been fatal for 2 lives and they seemed pretty casual including the driver. If such mentality continues, no wonder in future some more lives could be at stake.
Request transport and other concerned authorities take immediate steps and penalise the car owner. CCTV footage can be seen for the incident.

Regards,
SAIKAT MALLICK.
