> You can really rely on everyone driving a motor vehicle to obey practically every traffic law every time. That is, they stop for red lights, they stay in lanes, make legal/safe turns; they generally stay near the speed limit and don’t egregiously violate it. And they know that driving is a privilege and that violations can cost them their license, which will cost them their job, their freedom and a lot of things. What utopia do you live in? There's a major wreck at least once each year a couple blocks away when too many people speed while blowing the stop sign at the same time. There's a motorcyclist routinely going 115mph+ through our 25mph neighborhood, and despite having gotten the police to give him stern warnings on three separate occasions he still hasn't stopped (has slowed down to ~80 most days). The median minimum speed at stop signs is 10mph, which might sound safe, but it's faster if you happen to be crossing the crosswalk at the same time because they have to make sure they can get in front of you -- usually misjudging and requiring me to jump away. And you're right that people usually stay in their lanes ... on straight segments ... on curves I have to be prepared to take evasive action as some pickup truck inevitably borrows half my lane while I'm beside them. Sure, cyclists usually brazenly flaunt traffic stops, speed limits, and the requirement to share the road, but it's not anywhere near as bad as what the cars are doing.
