I was driving leaving the Airport in the left lane then their car passed me suddenly and the driver try to hit me and did the middle finger in a rude way. I talked to the company manager, she said she can not tell me what she did with the driver but what the driver did is not safety. They supposed to have GPS in the bus ti see what happened, if they did not have GPS so they are not require to be a public transportation, because it is not safe for any passenger.
