So where are we on this particular rendition of the Laffer curve? Are we already fortunate enough to be at "peak road," right here and now? That seems unlikely, but I suppose it's possible. Or would it be best to either remove more lanes, or add new ones?

Would traffic flow become infinitely fast if we removed them all?

Conversely, would it become infinitely slow if we paved every square inch of land in sight?

It's almost as if such simplistic models are worse than useless, huh.

I'd say that it's more like taking models to extremes is useless.

If your doctor says that you're consuming too much salt it is increasing your risk of a range of diseases, you don't turn around and say "But salt is necessary for the function of life, I can't just cut it out entirely!". The answer, as with most things - is somewhere in between.

With our current set of transport options - a mix of transport options are going to be optimal. The specific mix is going to depend entirely on the area and traffic patterns.
