Driving like Walter.
Self-driving cars will soon be upon us. But will they be fun?
Cars are becoming ever more intelligent and aware. They have anti-lock braking systems, electronic stability control, lane departure warning systems, auto-dimming rearview mirrors, headlight beam height control, dual-clutch transmission, automatic start/stop, vehicle-interval radar, and emergency brake assist systems. An automatic park assist system is one example of an autonomous driving feature that most people would agree can be pleasantly convenient.
Yes and no.
On the one hand, unlike their human counterparts, electronic control systems are not distracted by music, beautiful scenery, accidents in other lanes, phones, kids in the backseat, or passengers in front. We can therefore expect autonomous vehicles to:
- scan for approaching traffic before changing lanes,
- downshift and accelerate, if needed, to pass trucks (instead of spending an eternity trying to overtake them at essentially the same speed),
- pass tractors promptly as soon as the front radar gives the all-clear, and
- move to the right lane when slower speeds are preferred, in order to free the left lane.
Ideally, autonomous driving systems would provide a smooth, almost sailing sensation because the control units are on high alert, focused at all times on the traffic and immediate surroundings. Driving will become safer and more relaxed.
On the other hand, an autonomous car will hardly be able to drive the Nordschleife of the Nürburgring as commandingly and quickly as Walter Röhrl in a 918 Spyder. Even the cleverest computer lacks that sixth sense: the ability to instantly anticipate the results of different situations or behaviors. And, of course, it cannot match an intuitive feel for thresholds and limits.
