No, our cashless carpool transaction system is designed to protect both of you. All carpool transactions for TangoRide trips are executed within the app at the beginning of a shared commute to ensure there is no risk that a driver is not reimbursed properly, and so both driver and passenger know the total cost of the ride before agreeing to it. TangoRide community members should never pay cash to share a ride with a TangoRide driver and tipping is never allowed since this is purely cost recovery for the driver. Also, TangoRide automatically calculates the reimbursement cost for each trip, so driver and passenger avoid the uncomfortable feeling of having to negotiate the ride cost.
