So I don’t buy this argument, and I think it’s a dangerous one. The hyperbolic, oblivious version of what you’re saying is: “well, when there were many taxi companies, it was a Wild West with no tracking and little accountability, why should that change now that the tech lets you call a cab from a phone?”
The technology we use to hail cabs provides new business opportunities, and those are actively being pursued. But also the centralization of these operations also provides new regulatory opportunities — perhaps we should be taking advantage of those too!
