I sped up through the pedestrian cross walk when I saw people waiting to cross the road
Why would you speed through a cross walk?
I enjoyed the feeling.
People in crosswalks have the right of way and need time to cross. Going after them is rude and inconsiderate. Give people the space they need to make their crossing.
It's fun, the urge just came over me
You could have caused serious injury by doing that. You really need to wait for the people to cross next time.
