I'm going to tailgate people that drive under the speed limit to tell them to speed up or get over
Are you actually going to do that? I hope that is a joke.
I hate people who are late for work.
Doing that in traffic is bad. People are going to be upset at you and there is no telling what can happen.
I can do whatever I want for my own pleasure. If people don't like it, they can just leave the area.
People may end up trying to brake check you or something if you tailgate them. Just move around them peacefully if they are driving too slow for you.
