Even in the short term, an owner of a large (say 10k+) fleet of cars has a lot of opportunities to drive down cost per car that is not available to an average costumer: - a guaranteed purchase of 10k cars will get a significant discount over retail price - not paying dealer overhead - buying gas (or electricity) in bulk will be cheaper than retail price - in-house repairs and maintenance will be cheaper - a lot of people buy on credit, which is expensive. A fleet operator will be able to get cheaper funding (e.g. free by doing an IPO) and eventually fund purchases fully from profit - an average customer is influenced by marketing and therefore over-pays for non-essential items. A fleet buyer will be ruthless about maintaining best-bang-for-the-buck ratio. In the longer term fleet operator will transition fully to electric, build its own electricity generation capacity (especially in sunny states like texas or ca, where solar is really cheap), use data from past repairs to drive up reliability and durability of the cars etc.
