- Incentive optimization: how can we move the driver to high-demand zones while staying profitable?
- Real-time fraud detection & prevention: how can we detect drivers rigging the system & call them out while doing so?
- Ride acceptance prediction: how likely is it that a driver is in for the ride?
- Driver lifetime value: how long and regularly will a driver work for us?
- Client churn: do our clients still love us?
- And plenty more ...
