The best way to check the safety of any place is to travel in bus at night 馃槣 (No, please don't do that!) But I somehow do calculate the safety pointer with ease of transportation at night. Yesterday I had to take the airport bus in Bangalore city at night and it was perfectly fine. I had to take a cab at night and it wasn't a great experience. The drivers kept cancelling late at night. So I highly recommend taking an auto or any other service available to you rather than depending on online services, if you want to reach somewhere faster. Then again, is it safe? I don't know! 馃槓
