I 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.
