Moved to Hyderabad recently.been part of 2 accidents

Yeah. Shifted to Hyderabad with my new 2 wheeler. And guess what 2 times got into accidents. I don't really understand if i am a bad driver or is it the other guy.. Incident 1. Was on 2nd lane and had to make a turn to other side of road. But my judgement told me that i won't be able to because of traffic. So i decided to move to 3rd lane and stop. And when there was only a single bike far away in 1st lane near to 2nd lane. Was doing a sort of 45 degree, and the single bike with 2 ppl hit my scooty near foot rest in the 2nd lane. I fucking don't know how. Yeah i had given indicator. Incident 2. After a traffic check point was on 2nd lane mid. A car suddenly shifted from 1 st lane to 2nd lane with indicator and nearly his tail hitting my front. Dodged and got shifted to 3rd lane. Now the indicator off and the guy suddenly shifted to 3rd lane and braked. Boom my scooty hits his back. There was a tata car behind my back horned. I couldn't even recall when he stopped. It was so sudden and the driver was looking to left as if he don't know where be is headed.. Just can't understand whats wrong with me or the ppl are such bad drivers. Pls comment your view.
