Second, it is a widely known issue, that a slower mowing car is causing ripple-like delays far from the car itself. For example when a police car is driving inside the traffic flow. But if most of the cars are following the rules, like 95% of them, then one law abiding Waymo would fit just fine. In EU, with the deluge of speed traps and mobile patrols, most of the cars are driving under the limit, and honestly it feels fine. I'm originally from a country where +20 above was like a norm, and fast cars were +40 or more, so adjusting to EU took some effort. But now I don't even feel the need to speed, especially if it is 140km/h highway (86 m/h)

I often wonder about laws that are ostensibly there to prevent dangerous actions, about whether they actually help prevent dangerous driving.

This guy analyses tailgating: https://m.youtube.com/watch?v=6n_lR09sjoU Awesome software although he seems biased (e.g. no mention of pedestrians), but he does say that tailgating is much more dangerous than speeding.

I'm interested whether cameras will start to catch dangerous drivers. I regularly seeing drivers do very dangerous things. Yet we have no easy way to train them (for those that care but are unaware), or catch them (for the antisocial that don't care).
