There are different levels of errors. Something like a negative number for a fare is a serious error in every circumstance and should ping the billing team in their Slack channel (or PagerDuty) immediately. Something like a small positive number, while still concerning, is harder to calculate and harder to justify a critical alert for. For example, Uber does have a feature for drivers where they can type in where they are going (eg. for a personal errand) and be connected to a rider going the same direction, and the fares on those trips pay fairly small amounts of money.
