The problem

Friday, 2 a.m., the bars in the city centre close. 400 people open the ride app within ten minutes, and each one wants the closest car.

Last month two riders on the same street were sent the same driver. One of them waited 12 minutes for a car that had already left with the other rider.

The ops lead asks for two things: the nearest free driver gets the offer, and a driver never holds two offers at once.
