Exactly. Rush hour is like dumping 5gal bucket into a sink. You'll always be bottlenecked by the drain but a better drain will mean all the drops get where they're going faster and with less waiting around.

Let me guess this straight, the plan would be that:

1. in a global environment (the following steps are done everywhere around the world)

2. where maximum speeds, though:

- clearly marked everywhere

- mentioned during driving lessons and driving codes/books

- part of the written driving exam every driver has to pass

- enforced by police, cameras, a myriad of automated systems etc

3. are still ignored by, say, 40%+ of drivers

... so, the plan would be that in this environment, mandating minimum speeds would actually improve anything? :-)))

I'd be super happy to read the study proving this. Where by study, I mean actual physical trial.
