Sex in self-driving cars: Passengers are reportedly hooking up in San Francisco's driverless taxis

• Riders are reportedly using San Francisco's self-driving taxis, operated by Cruise, to hook up.
• A 2018 study predicted that more autonomous vehicles could mean more sex on the road.
• The cars have cameras and microphones for safety, and Cruise prohibits "inappropriate behavior."

With no one in the front seat driving, some people are using self-driving taxis for a little bit more than just transportation.
