There wasn't much in the way of innovation in Uber/Lyft. Private Taxi companies and the regulated cab commissions were able to get competing apps going pretty quick. They just couldn't compete because they had to charge some kind of fee to the Taxi operators, while Uber was giving users a huge discount.

The venture capital firms knew from the beginning that Uber wasn't about technology or innovation, it was about being the next tech monopolist.

Get in between businesses and customers in an industry that's going through a technological change. Subsidize to the benefit of the businesses and the customers to prevent competition. Grow until you have monopoly power. Increase the costs to the users, then increase the costs to the businesses. Next step is usually offering to sell the customers to the businesses(usually by selling ads), but I could see it being some kind of Uber driver gold subscription or something that gives you priority in the app.
