Will this stop drivers from using cell phones? This is a post event solution. This solution might work but requires police, judges, witnesses, cameras, and many components to properly implement.

One way that Amsterdam or Copenhagen would fix this is to reduce the number of lanes. They purposely remove lanes (even when the street can accommodate extra ones).

They also introduce shrubbery on the side of the road that blocks human vision. This is because if you can't see past the corner you slow down as you approach.

Another solution is changing the texture of the road. We naturally drive slower on cobblestone versus smooth asphalt.

I've also seen speed bumps or even just a slightly raised smoother bump on a highway/road in honolulu and in colombia to slow drivers down.

There are many well understood road engineering solutions to use.
