If we put railroad tracks down on space where a bus lane is and asked anyone would you ever stop your car on the railroad tracks, the answer would be no. The idea that 30 tons of steel is going to come down the street is enough of a deterrent. ... We all have an explanation about why entering a bus lane is a little thing and it’s okay. And the fact is that it’s not okay—the fact is that 75 to 100 people on a bus are held up over that.
-- MTA Chief Executive Jay Walder
