6 a.m. to 10 p.m. isn’t remotely peak, and downtown usually doesn’t extend north of the river. To extend it to the mostly residential zones between Chicago and North avenues is punitive, and despite what progressives would like people to believe, lots of the residents in that area aren’t rich. They are young professionals with two and three roommates to help pay the rent or living in a tiny studio apartment. They are also at the final stages of a number of very popular bus routes, and actually getting on a bus at, say, Chicago and LaSalle at 8 a.m. to get to the Loop might mean waiting through three or four buses with no available shelter in pouring rain or punishing cold. Who wouldn’t opt for door-to-door service for only a couple dollars more than the bus at that point?
