Uber announced they will be banning their passengers from flirting, touching and having sex in the backseat of their car. In their updated Community Guidelines, it now says,
“As our community guidelines make clear, you shouldn’t touch or flirt with other people in the car. As a reminder, Uber has a no sex rule. That’s no sexual conduct with riders, no matter what. And you should never hit or otherwise hurt a rider.”
If for some reason you need to get it on immediately and you’re in an Uber you risk getting banned from using their service. So resits the urge and get it on after your ride.
