Imagine a market where there is one food delivery company rather than ten:

a) at a restaurant, rather than having ten different delivery people pickup, One person can pickup ten orders.

b) 10x more consumers means that the average distance between deliveries shortens.

It’s not going to be quite this efficient but directionally more scale means more efficiency.

In addition, less competition means that Uber can charge more for their services.
