I would LOVE to develop an Uber clone and pitch it to Governments around the world. We could even link them up so you have one unified account for people who cross borders.

The government and taxpayer could then take any profit (or operate at a loss / break even if they want to subsidise costs for their citizens). The customer acquisition / marketing costs would be almost zero if the government mandates it as the only or preferred ride-hailing app.

I don't really think Uber is going to innovate much from here (e.g .how much has the uber experience changed since UberX was rolled out?) outside of self-driving cars etc. there's no reason why we need a private company to innovate further, and there's almost no risk in doing this.

It would be seen as a natural extension to mass transit, and every government around the world should be providing it for their citizens.
