ouch. guess nobody notices that people STARVE if it take a very long time to get to a location (aka WALKING).
A very SIMPLE solution is just changing how cars/trucks move. Basically watch the traffic. you'll notice cars stopping, but very SLOW to start moving again. cars behind them suddenly have the same issue. cars in intersections and in buildings (garage, contruction, teamsters, etc) will REFUSE to get on the road if there is even a hint of a car driving by.

Simply by speeding up their reaction time (and max speed) would greatly improve traffic flow.

Too bad they have already announced they will do NOTHING about the traffic issues.
