I mean, some drivers do drive dangerously, but that's not what I'm talking about. With the narrow network of one way roads, going down an alley or going the wrong way down an empty one way road for 20 feet can sometimes make a 15 to 30 minute difference in trip time. And in traffic, it can be hard to get across some intersections unless you block the intersection. None of these is dangerous behaviors, per se, but they can be difference makers for riders.
