I wonder if the Walmart strategy of destroying your competition by undercutting prices can work for Uber. Is the barrier to entry for an app-enabled personal transportation service that high?Therr are also many substitutions for the service suxh as driving one's own car, carpooling, actual ridesharing via a platform, mass transit, biking, etc. There are already open source implementations of this and ride sharing. I apologize if this sounds misinformed, but as tech advances and platforms such as these become more mature, could we not use some of the principles established by blockchain to create a rating system that is open/transparent so that drivers and passengers can just directly transact with each other? Personally, I like Uber/Lyft's service but I dont find the price to be a. bargain. As it is, I primarily use it for transportation if there's is a chance that I may be drinking alcohol or when parking is going to close to thr cost of a ride
