I sometimes drive exactly the speed limit just to annoy the people behind me
What is the reason why you are choosing to drive slow?
I am not sure of the reason. I am getting all this energy from these slow drivers.
You're not in the wrong for driving the speed limit. If it's what you want to do, you're more than welcome to do that. I just do not recommend doing it to be an annoyance to others.
But I enjoy speeding, I always go way over the limit.
It's understandable to want to get to your destination quicker. But you should be careful about speeding, it could potentially get you in trouble with the law.
