Today, lots of new cars are equipped to handle slowing down and speeding up all on their own, using nothing but radar-guided cruise control technology.
A step beyond that are systems that can also navigate stop-and-go traffic, like VW’s Traffic Jam Assist demonstrated in this video on-board a new-generation Tiguan SUV. As you can see, the system is not exactly foolproof.
While useful, any system that falls short of Level 4 autonomous driving will never allow the driver to fully relax behind the wheel. So by intervening, the driver is basically doing as much work as the driver assistance system, even if it’s only in intervals.
Furthermore, this tech can lead to situations where the car’s electronic “brain” makes a mistake and you’re suddenly drifting too much towards the lane next to you – and that will put a scare into any driver who expects the on-board computers to be infallible.
As for how this Tiguan performed, well, you be the judge. The driver insists that the car isn’t actually pulling to the right that much and that the placement of the video camera is the real culprit there.
However in the comments, he does acknowledge a couple of misfires, specifically at the 1:30 and 2:07 minute marks.
