Computer models of adaptive forward lighting

We make our way off the highway. On the surface roads it seems much darker, and I flip on the LED headlights. The adaptive forward lighting system is quite helpful on these winding roads. Yes, I know that light doesn't bend, but it almost seems like it as the beams move their pattern in conjunction with the direction of the vehicle.

Finally we have arrived at my husband's office. He offers to take the wheel, but I turn him down. Driving just isn't as stressful now that cars do so much of the thinking for you, so I don't feel as wiped out as I might have back then. "And don't forget," I remind him, "The seat is calibrated for me." The car company designed my driver's seat specifications just for my dimensions — measuring my seated height, my hip width, the distance from my knee to the pedal, my arm length, and so on — so that it really is a custom fit. Even the stiffness matches my personal preference.

We're on the home stretch now of our commute. I flip on the infrared-laser night vision to improve my visibility on our unlit country road. The laser headlights are invisible to my eyes, but a video image of what's reflected back shows up on the windshield display, right in front of my field of vision. Oftentimes the system picks up raccoons crossing the street or other night dwellers I might otherwise miss — but tonight the coast is clear.

I swing into our driveway. Everyone unclasps seatbelts, grabs bags, climbs out. All the doors slam and I press the remote locks. As we all walk up the dark sidewalk to the house, the car emits a warning beep. We left the baby in the car! Of course we would have noticed in another moment, but I am ashamed to tell you how many times the Interior Occupant Sensing System has gone off. The low-energy radar senses the combination of motion and rising temperature inside the locked car, and alerts the surroundings that there's a child or pet in the vehicle. I hurry back down the walk and extract the baby from her car seat.

Another successful family commute — we all made it home in one piece, with no small help from the car itself. Honestly sometimes I think our car is smarter than we are! Scientific American Frontiers
