&gt;I cannot think of any service that limits itself to an exclusive client list yet is cheaper than the same service that is open to a wider client base.<p>Exclusivity doesn&#x27;t have to make a service more expensive. It may be possible to reduce operational costs by only allowing self-driving cars in a parking lot. The upfront costs might be higher (but not necessarily). If there is enough demand, it could be economically feasible.<p>Imagine a future where Level 4 self-driving cars are ubiquitous - the car would drop you off, choose the best parking lot (closest, cheapest), drive to it and park itself automatically.
