If people can be nudged by street design or transparent B-pillars, they can also be nudged by heavy penalties that are commensurate with the deed.
It would be far more effective if you applied a $5 fine every time a person looked at their phone screen while driving than if you instituted the death penalty which applied only when a distracted driver kills a pedestrian.

The claim they lowered drunk driving deaths by 1/2. I have no easy way to verify that but if true it certainly suggests people's behavior can be changed
This does not discourage drunk driving as much as you would think. It does remove a lot of the drunk drivers from the road by force, however.
Edit: Claiming credit moreso than flawed statistics, although both are highly questionable.
