In Ottawa Uber has promotions for different areas. Downtown usually has something like a 1.5x promotion. I don't understand what that means. If a regular fair is $4 and it is in the 1.5 promotion area does that mean it would pay $6 instead? What happens if you pick up a meal from within a 1.5 zone and deliver outside that zone to an area that is 1.2x or no rating? What if you pick up a meal in a 1.2x zone and deliver to an address in a 1.5 zone? I was delivering in a 1.2 zone and had to make a delivery that took me to a 1.4 zone. The 1.2 zone had been a little slow so I thought the 1.4 was an indication of greater demand for deliveries and reduce supply of drivers. I waited 10 to 15 minutes and nothing. Headed back to my 1.2 zone and received a delivery right away. This has happened a few times. I do not see the need for increased deliveries in the higher zones. This has me wondering what the zones really mean.
