Yes, that I think is the best of the social engineering ideas presented in that video, its also one of the easiest for the city to implement in terms of infrastructure.

Most of the people it would effect are cab drivers/drivers-for-hire and delivery trucks/vans. Everyone else who drives daily in the city is, imho, an asshole ;)
