If you're in the road on a bicycle, please stop for red lights and stop signs.

I've seen this happen twice in the last week. Bicycles just sailing through red lights without stopping. Please be smart before you get hit by a car. And please stop switching between the sidewalk and the bike lane when you hit an inconvenient light - it makes you unpredictable and it's dangerous. I doubt any of those riders are reading this subreddit but hell....

edit: Cars, too, of course. But I've been seeing a lot of bicycles doing this lately, and it makes me panic that I'm going to witness something tragic. Please be safe on the roads, whatever method of transportation you use!
