Sometimes I like to ride my bike on the sidewalk instead of the bicycle lane.
Why do you want to ride your bicycle on the sidewalk?
It seems a bit safer from cars.
You should follow the laws of the road when you ride. You could hurt someone if you hit them on the sidewalk.
It's not like I'm always riding on the sidewalk... just sometimes.
You'll be breaking the safety laws put in place if you drive your bicycle on the sidewalk. What if you run into someone and seriously injure them? It is safer for you to bike in a bike zone instead.
