I do not think that history will repeat itself. In the case of GM, they were looking to make/sell more cars to make more money. Lyft/Uber want to dominate ride sharing on all fronts and they do not really care if more cars are sold. In fact I'm sure they wish less people would drive, so that all people who did drive would drive for them (pipe dream will probably not happen). The battle that is about to take place is which system can be in more cities, deliver the best product, and make the most money. Imo this is going to be a good and bad thing. It will be good because the software side of things will improve and they may have more connectivity throughout the ridesharing experience. But it will be bad due to the fact that Lyft and Uber, to some extent (they do have a small fleet of self-driving cars out west), do not currently have vehicles that they must maintain. The real issues they will face is not in NYC or in cities that are already established, they have ample employees and teams that know what needs to happen, it will be in any cities that they look to expand. I do not think that the bad out weighs the good that can come from this but it will be an interesting time within the six to eight months after any kind of purchase, if it does actually happen.
