Good on you for letting the bus driver go ahead of you, the other day my older sister was driving and she was going to merge lanes to give a bus driver more space to merge into her original lane and when she indicated, checked and then started moving, someone on their p's sped up and almost hit her and also beeped at her, if my older sister would've been hit it wouldn't have been her fault as she had checked and the other driver sped up, so thank you for being a responsible driver.
