I think the problem really is profit. Pepsi and Coca-Cola both sell sugar water, a commodity, at a profit. Lyft and Uber have made rides a commodity but at this point it looks like commoditization of rides is not able to be sold at a profit. I think they both are touting that scale and technology will lead them to profitable rides but its not obvious that this is going to ever come true in a way that justifies their…
In my opinion the outstanding question today is: are they both too early? It's currently a race to the bottom of driver oriented rides. As soon as driverless becomes viable the current rider fee suddenly shifts to being a more positive profit margin and also shifts opex back in favor of both. But can either last long enough to get there?
Alexa can't even turn on my living room lights more than 50% percent of the time. I'm not holding my breath for driverless cars coming any time soon (if ever).
