Yes there is a hard floor with the price, but there are two ways it could go lower even without driverless cars. The first is Uber&#x27;s indirect vehicle costs (borne by the driver, but ultimately affecting the price floor) are very high. The drivers don&#x27;t have any economies of scale in running and servicing their vehicles. A competetor that is optimised for running costs could undercut Uber.<p>The second way a competetor could undercuts Uber is by accepting a lower return on capital. Uber&#x27;s cost of capital is very high compared to the cost of capital in the utility industry. It will be very hard for Uber to compete long term against a rival with low cost capital.<p>My expectation is Uber will win the battle against its venture backed rivals and will lose to a new competetor optimised for running and capital costs.
