Look, what started out good — let’s exploit a business about the shared use of the most wasteful product around, the car — ended in disaster. Rule of thumb is that cars take up space 95 percent of the time unused, costing their owners a bunch of money. However, owners began to use their cars full-time to be able to make a living as Uber drivers, which suited Uber fine in its ambition to put a serious dent in the personal mobility market. The result? Uber cars add to more traffic. Uber chauffeurs keep making more working hours to offset their dwindling income, and authorities decided to give the so-called independent contractor status of chauffeurs a serious second look. In London they are already seen as employees, which Uber is appealing. In California they want to do the same thing.
