The Colorado example is about no longer giving out carrots rather than using any type of stick. Tolls and higher taxes would be examples of sticks. > clogging

The Colorado example is about no longer giving out carrots rather than using any type of stick. Tolls and higher taxes would be examples of sticks. > clogging the roads The roads already be clogged and adding more lanes is not likely to unclog them. Single occupancy vehicles at the end of the day are not a solution for moving hundreds of thousands of people around - there's an intrinsic scaling problem that can't be solved by building infinite roads. It's kinda like trying to get high speed internet by adding more & more 56k modems.
