This couple have sex in the ML witnessed Passenger Train

This couple is having sex in metro ML Vienna.  When the other passengers realized what was happening, they ran over and then, slowly but surely, creeping back to watching, cheering, taunting, take photos, and create an alias record movies with hp.  Is this a sign of moral depravity getting worse?  how come in the carriage passenger train in the crowd witnessed a lot of people are so busy they remain absorbed in dipping and rising sex ..  : D
