They're all encouraging more driving, which leads to more pollution and more pedestrian deaths. 20mph speed limits reduce collisions, reduce the severity when they do happen, decrease pollution, and barely has an effect on journey times.
I thought 20mph speed limits just resulted in cars speeding more and going significantly faster than they would otherwise. Drivers don't really care about speed limits, they go as fast as they feel comfortable. Therefore we should make drivers as uncomfortable as possible.

From the data I've seen, there is an increase in non-compliance, but also a reduction in average speeds.
