I drive an Uber XL. Most of my calls are for an Uber X. At times, I will show up and the rider wants to put 6-8 people in my car. At times I have made them cancel the ride, pay the fee and then relist for an XL. The XL says up to 6 passengers. My car holds 8. Is there any additional liability if I take more that the Uber max of 4 or 6 passengers? How do you handle too many passengers for the car listed?
