Oh my gosh! I almost ran over and killed a skateboarder
What kind of skateboarder was he?
One doing stupid tricks in the middle of the street
When driving a car you are responsible for watching for road hazards. Pedestrians always have the right of way in the road you should pay attention so you don't kill people.
I am not responsible for other people, it's the mayor's responsibility to make the city safe for stupid people.
It may seem unfair, but you really are responsible for watching out for others while you're driving. People are unpredictable, so accidents can happen easily if nobody is being responsible.
