Today I was cutoff twice... by the same SUV.
The first time- whatever, I anticipated it. The car had the "I'm a princess" aura around it and I gave it space. Sure enough, no signal and over it came cutting me off.
I was already covering my controls so adjusting speed for a safe following distance wasn't an issue.
We continued and the SUV went to the left lane to try and take advantage of some room. I kept my place in the left part of the right lane for visibility and kept on trucking.
Boom- the car was back in my lane.

He could have made more progress from staying in the left lane but yet again, no signal and this time I had to swerve right and really use some breaking. For reference my front tire had been next to his rear tire at that point.
I've doing my best to stay calm and not do anything stupid so my good samaritan takes over.
When we stopped at the next stoplight I lane split next to him. Knock on his window and let him know that his tail lights out.








What I wanted to say? "I'm sorry sir, I just wanted to make sure you knew about your lights. I had no idea that you were just a huge "O Ring"" The responsible way seemed to work better
I pulled up in front of him and was on my way.
