Actually it turns out is a pretty great idea, it's called Uber (and Lyft).
I was commenting specifically on having it operated by teenagers. Do try to keep up.
Driver inexperience + pressure of a random stranger + parts of town they don't know == bad idea.
It has nothing to do with knowing the location of the destination address or the best route there. It has everything to do with not knowing the roads. Not being an expert at merging, not being expert at parallel parking, not being expert at sizing up complex, unfamiliar intersections.
Saying, "no problem they have a GPS" is like saying we should let teenagers fly passenger jets because they have autopilots.
And given the way most taxi drivers drive I frankly would in fact rather be driven by a teenager.
Nice rhetoric. Studies show cab drivers are less crash prone than regular drivers per hour behind the wheel. Teenagers (new drivers) are significantly more crash prone than the average.
As for the "random stranger" thing that part simply shows your unending ignorance into how Uber and Lyft actually work. It's not strangers that meet, it's two vetted individuals.
Two 'vetted individuals' that have never met before are still strangers.
