Does public transit pick me up at my front door and drop me off at any location I choose?
Does public transit take of the minute I leave the house?
Is public transit available 24/7, even in remote areas?
Does public transit wait for me to load 2 kids, a dog, 4 suit cases, and various bags, blankets, and toys?
Does public transit turn around after 2 minutes, bring me back, and wait for 30 seconds because I forgot my wallet on the kitchen counter?
Will public transit still work during a public transit strike? (yes, this actually happens over here in Europe)
No? Well, then you can hardly claim that "public transit would do the same" as a self-driving car.
