> that's frustrating for everyone behind them in the best case at best... and I imagine possibly even more dangerous in the worst case, no?
No.
Waymo put the myth to bed [1]. Even if you might piss off a speeder, driving the limit in speeding flow remains safer as the handling advantage (frequency) and exponentially-lower energy in the event of a collision (magnitude) dwarf other effects.
Your link is about Waymo. It doesn't imply the same is true for human drivers. When I search around whether driving too slowly is too dangerous, basically every source I see says it is. Random example:
if slow driving wasn’t as dangerous (if not more), highways would not have minimum speed. would you personally choose cars driving 15mph on a highway you are on or 90mph? between those two choices, I’d choose 90mph any day of the week and twice on sunday
You must live somewhere warm. On Canadian highways 15 mph is just a fact of life a few times a year. I've never seen a Canadian highway with a minimum speed.
Of course! I did not mean that anyone should ever drive any speed that is too slow for given conditions, I have driven 5-10mph on higways with minimum speed of 45+mph during inclement weather.
I live in the USA and can tell you with 100% certainty that if I drove 15mph on a highway drivers that pass me will call 911 and I will be pulled over. driving 30-40mph over the limit is unlikely to trigger the same concern from other drivers unless I am “street racing”
