Tipping is not mandatory, but in 2026, it has become a standard "peer-to-peer" expectation for good service, especially as driver operating costs for fuel and maintenance remain high. Most riders tip for a clean car, a safe route, or help with heavy luggage. A common rule of thumb is 10% to 20% of the fare, similar to restaurant tipping. However, if a driver is unprofessional, the car is dirty, or they take a needlessly long route, withholding a tip is a perfectly acceptable way to signal dissatisfaction. Uber's app makes it easy to tip after the ride is over, and interestingly, drivers can see which passengers are "frequent tippers" through a subtle rating influence, though your actual tip amount remains private until after the rating is submitted. If you had a standard, "A-to-B" experience without any frills, a small flat tip of $2 or $3 is a gracious way to acknowledge the driver's time and effort in the "gig economy" landscape.
