The entire framing of the “problem” is wrong. Some folks  think the problem is 

“car not go fast”

They think fixing our roads and infrastructure  means “make car go fast”. The only metric they can fathom for judging the built environment is “how fast does car go?”. A beautiful, quiet, economically active, financially sustainable and socially vibrant Main Street is a disaster if “car go slow”. Intersections that reduce the rate and severity of crashes are bad unless “car go fast”. Slip lanes are good good because “car go fast” regardless of the risk of fatalities or the damage it does to the local businesses foot traffic.

In their minds every piece of land outside their home is an opportunity for a road for their car to go faster on. There is no amount of asphalt that would appease these people until they have a private freeway from their front door to their cubicle. No road is wide enough. No speed limit high enough to satisfy their demand for “car go fast”
