Once, just once, I would like a traffic routing or analysis system to comprehend the concept of lanes. There's no point coloring a segment red if I'm turning right, when all the slow-moving traffic is waiting for a left. Anyone who spends more than a day driving a car in a populous area will recognize this. I noticed that Traff can represent blocked or closed lanes as individual events, but otherwise considers "fast" and "slow" traffic only at the scale of streets and roads. Guess I will be waiting longer, still.
