40% of the city also doesn't drive, because they cannot afford a car and thus do not own one.

Transit is not one size fits all. Its providing as many options as possible to give as many people as possible access. Its multi-modal, and requires enablement of all kinds of different use forms - bikes are generally the optimal vehicle for an able bodied person living in a city, but bike lanes are also for powered chairs and scooters. Getting bikes off sidewalks make them safer for pedestrians and strollers. Reducing car lanes makes the whole outside built environment safer for people in general. Getting higher frequency more reliable busses lets people forsake car ownership and thus reducing crowding in the public space, again. Building an actual metro would make Baltimore a real first class city because it would get you around faster in the city than a car ever could.
