Don't get me wrong, I'm all for more pedestrian friendly roadways, but there are times where I find myself seriously considering vehicular homicide.
This happens about 90% of time on campus. You'll be breezing along, being alert, watching people walk along the sidewalks. You think, there are no crosswalks around, no one could cro-AGH HOLY SHIT! *screech* and some dude with headphones stuffed in his ears casually strolls across the roadway, often after emerging from a patch of bushes. You sit there, inches from him, thankful no one rear-ended you.
Crosswalks are there for a reason, you can't just cross anywhere on the road and expect people to be cool with it.
