> I'm imagining biking down Market St, 8 months pregnant, with a toddler seat and two kids in tow. That's a lot of faith that nobody's going to open a car door at the wrong time or pull out into traffic without looking That's why it's important to ride where one can be easily seen. That means riding in the middle of the general purpose lane and not off to the side in a narrow bike lane within the "door zone". I ride with my three kids (one in the rear child seat and two in the trailer) in the middle of the lane and never had problems with car doors or vehicles suddenly pulling out without seeing me.
