Side View Mirrors
Most modern cars designed within the last five years or so have complete parking cameras that can show you a 360 view of your vehicle on a dashboard screen. If completely accurate, it saves you the trouble of craning your neck to look past blind spots. And nearly all cars beep when you move too close to another car, object, or person.
Most devices now operate with fingerprint or facial recognition technology. That means you won't have to rack your brain trying to remember which variation of your password is for Facebook, and which one is for Gmail. When Apple introduced facial recognition, it totally changed the game for smartphone security.
