The bike ramp example was insane to me. OF COURSE it's not built so cyclists can zoom up onto the sidewalk at 20 miles per hour without slowing down. That's how you turn a pedestrian into paste.

Really, you should be dismounting and walking your bike onto the sidewalk, but if you're going to ride your bike up that ramp, absolutely do not do it so quickly that you risk crashing.
