And do they cook one food order at a restaurant they work for, then 15 minutes later walk across the street and cook for a competing restaurant for 30 minutes, and then immediately walk back across the street and cook a food order for the other restaurant? No, of course that's not normal.
This will ultimately accelerate the ability of the strongest companies to destroy their competition and potential competition. If Uber doesn't bleed to death financially first, that will be Uber due to their global scale.
Uber may not realize it because they're stupid, but this bolsters survival of the strongest in the segment. They can easily kill off competition using this by eating the labor supply. Someone that would have previously worked for multiple companies - trivially flipping between services as it was most ideal for the driver to grab a fare - will no longer be available for multiple companies at the same time. They'll now largely hold a normal job and will not want to work for multiple companies, pulling two shifts per day. Sure, there may be exceptions of drivers that want to pull a weekend job with another service or work two jobs per day, but exceptions is all they'll be. This will narrow the market winners dramatically and quickly.
Monopolize the market, consume the labor supply, raise passenger fees, lean in to killing off the competition. It's super simple.
If I were Uber I'd abuse the stock market for funding to pay artificially high wages to the labor supply (get all the best drivers), and I'd hire more drivers than I absolutely need (deprive the competition), and begin this killing process immediately. I'd go one market to the next, using Uber's market cap as the funding base to monopolize each market. This type of ruling makes labor supply a competitive advantage to whichever company can acquire the most and best drivers. A global ride hailing app will be advantaged over the smaller local/regional competition accordingly.
The next ride hailing app in the market that wants to get started will find no available labor supply to compete with. Welcome to competition stagnation.
And of course then the moronic regulators will come back around, having created a monster, and they'll have to pursue anti-trust (or the equivalent) against the market winner they helped to cause.
