Sensors and software monitor the area around the vehicle
Just a second ago, a glance in the side mirror still showed that everything was clear behind your vehicle. Then, in the blink of an eye, the driver of a car lurking in the blind spot behind you honks his horn just as you’re about to change lanes. Later, you arrive at a T-junction and look to the right. There’s no car in sight. It’s the same when you look to your left. You begin to drive forward, when suddenly a motorcycle appears out of nowhere on the main road to your right.
