Yeah, I commuted by bike until we had kids. Sadly, the preschool that we liked the most also wasn't easily bikable from the house. The kids now go to a school that is easily bikable, and it's a joy.

I do that now because I'm fortunate enough to live very close to work, but that can be really difficult for parents. If your commute time is too long then commute + work + commute can end up a longer span of time than the gap between breakfast and dinner for the kids. When I lived farther, I drove because that mattered more to me than missing meals with them.
