No. Their kids were doing the same, or taking metrorail or busses and walking the rest of the way. Some of them took bikeshare to metro to get to school in the morning as well. These are city kids who had been walking up to a mile and a half home from school since 5th grade. Even when the mother isn't working and could pick them up, the kids usually prefer to walk. It's an independence thing and their friends are all doing it. They walk with their friends, usually swinging by one of our neighborhood corner stores on the way. We are not talking about a demographic where gang activity is a problem.
In my daughter's case, she attended schools in the neighborhood through 8th grade. The kids in her class then dispersed for high school; no more than three of them were in any one high school. Almost all of them went to Catholic high schools. They were all over the city and several of the closer suburbs as well. My daughter ended up across town. To get home, she took a city bus that picked up a couple of blocks from the school (in a good neighborhood) and brought her to Union Station at the foot of Capitol Hill. That left her about a mile and a half to get home. That's where bikeshare came in.
P.S. I should add that my daughter certainly had many classmates from suburban areas who needed to be driven each way. Their parents tended to go green with envy of the city kids who could get themselves home.
