Oh, and the documentary i mentioned to you about Bogotá is on YouTube now
Cities on Speed: Bogotá Change
My favorite initiative Antanas Mockus started was he hired clowns to stand in intersections and make fun of drivers that disobeyed traffic laws

His reasoning was that Colombians care more about looking foolish than being fined.

I think something like that could work here:

Like, every day video an example of terrible driving and shame the person. Maybe follow them home, ask them what was so important that they had to risk the safety of other. Then they’ll say “well, i wanted to watch game of thrones” and look foolish.
