4. Self-Driving Cars
Tesla may have introduced its autopilot feature a couple years back, but that’s just scratching the surface of what the self-driving cars of the near future will be capable of. Soon, you’ll be able to take a nap on the ride home or read a book as your car perfectly navigates to your driveway. Running late? Tell your car to drop you off and it will park itself! This, more than perhaps any other futuristic gadget on this list, will change the way we live.
