This is a serious question, and it isn't about whether it is right or wrong or legal or allowed. I am just very curious as to how often this practice happens, whether the parents call Uber for their kids or teenagers just use Uber on their parents' credit cards. (likely with their permission)
To you drivers. How often do you run into minors? Can you provide percentages? say, X percent that are definitely minors and you check their IDs. Y percent that are iffy but you don't know. and Z percent being the rest - legit rides.
