They can use it to start fixing the roads, not the cars.
Just look at the cross intersection they use as an example, typical of the US. The ROAD is the death trap there. People are crossing each other at high speed, this is the BUG, and should be fixed.
The proper solution is putting there a roundabout, and you will have instantly less fatal accidents.
The US was the first to use roundabouts, but those early designs did not work well, and as a result we have those monstrosities like in the picture all around the US.
With electric cars that record accidents, the first bugs that we should fix are those in the roads, like those concrete barriers that have no smooth transition but a front wall out of nowhere.

- Laarlf 6y agoI live in Germany. We have some roundabouts. And let me tell you: they rarely work better than red lights. Traffic flow requires more than roundabouts. They require proper planning, green waves, proper sizing and still different lanes for roundabouts. Don’t forget about semis either. Just throwing roundabouts somewhere won’t solve anything. I’ve seen that often enough. That will just create more traffic jams.
- igorkraw 6y agoThe literature says differently, and is also aware of your opinion. https://www.safetylit.org/citations/index.php?fuseaction=citations.viewdetails&citationIds[]=citjournalarticle_63289_19 https://www.safetylit.org/citations/index.php?fuseaction=cit...
- Laarlf 6y agoUndersized roundabouts with 1 lane are not fitting for certain places. As said, I have seen many traffic lights being replaced with roundabouts. If you go to the Netherlands you see how roundabouts are executed well. Also Denmark has well made roundabouts. Just putting a small roundabout somewhere without putting thought into it is making things considerably worse.
- imtringued 6y agoI wonder who the insane engineer is that thought a 8 lane cross intersection is a good idea.
- LockAndLol 6y agoThe one paid and told to: make an 8 lane intersection there.

- zip1234 6y agoI do agree that road design would drastically cut down on excess speed and crashes. I'm not so sure about roundabouts as a solution though. Roundabouts may be useful to allow more cars to travel through a place but they are not great for other road users. I think you are also correct about the speed. Cars are mostly driving too fast. We have the tech to solve this problem today in a rather straightforward manner but the very idea of it makes people go crazy: speed governors on vehicles. The funny thing is, some places have them mandated on things like scooters and e-bikes, but a car with 700 HP that can go 180 mph does not have one and drives on the same road. There is a LOT of low hanging fruit.

People are only "crossing each other at high speed" in these simulations because the scenario involves someone running a red light: > Here, for example, you can see on the bottom of the screen that the simulated Waymo Driver avoids a reconstructed version of a real-life fatal crash by obeying the speed limit—and not running a red light, as the initiator did in real life [emphasis mine]... I don't think "roundabout all the things" is the answer to every traffic and road safety problem. This looks like an intersection between two 3/4 lane roads, and you'd need monster roundabout for it that seems like it would be confusing and/or slow. Also, a road can "have instantly less fatal accidents" by being closed or turned it into a traffic jam. IMHO, the road engineers need to balance accident avoidance, throughput, and user-friendliness.
