[Robbie Williams]

Hi, noob here, recently I've had people behind me either with their lights on or flashing them at me in races and sometimes in qualifying. I understand when people do it when they're on their flying lap to let you know where they are and to get out of the way but in the braking zone of a corner halfway through the race? Seems malicious to me. It's really distracting especially with the virtual mirror. So are there any rules against this or is it just something you have to deal with and not let it bother you?
Thanks
