Save fuel, get through traffic quicker and perhaps also safer. Nothing not to like, very clever.
In Barcelona and Madrid motor bikers get pole position at traffic intersections. The pavement is marked with a yellow grid (Barcelona) or bike icons (Madrid), bikers scoot ahead of the cars and busses for the light change.
Economic incentives work, this saves fuel and time for the more fuel-efficient minded motor bikers. If this ever were to happen in NYC I might get another bike, I bet there are others who would too.
