Even if you've never used an app-based ride-sharing service, you are probably familiar with what they are and what they do. The leader in this relatively new industry is a company called Uber, which operates a smartphone app of the same name. Its next biggest competitor is Lyft, a similar operation.
Ride-sharing services are hugely popular, in part, because they allow regular people to use their own cars in order to take on part-time or full-time taxi-like services. Customers love ride-sharing because it tends to be much cheaper than traditional taxi fares. But in the process of muscling its way into some 300 cities around the globe, Uber has stepped on more than a few toes and engaged in business practices which may not be entirely legal.
