you use mass transit (buses, trains) normally, and you use personal transit (taxis, cars) in emergency situations like the comment was referring to. I think that’s what they are trying to say.

Also, buses, trams, and trains CAN be much faster than cars if they are built correctly. Going to a mall in the center of a >1mil population city is much easier and faster on a metro than a car.

Don’t think of buses in a vaccum, consider other modes like rail and bike paths as well.

You don’t walk to a freeway, get in a car and get off the car at the end of the freeway to walk right?
