Dynamic pricing takes effect when a lot of people in the same area are requesting rides at the same time. This means that rides will be more expensive. Adjusting the price attracts more driver-partners to an area so everyone can get a ride.
You can wait a few minutes while more driver-partners get on the road, or you can pay a little extra to get a car right when you need it.
You're notified in-app if fares are higher than normal.
