With a considerable delay, Mercedes-Benz is now bringing its Drive Pilot system to automated driving.
It's expensive and doesn't do much, but it does more than most of its competitors.
Customers have to decide for themselves whether the opportunity to temporarily let the steering wheel out of their hands at low speed in a traffic jam or in similarly manageable situations is worth the money.
In any case, it becomes obvious how far removed all manufacturers are from their promises.
Even the assistant from Tesla, called Autopilot, can't do much, there are repeated reports of failures, sometimes of terrible accidents.
The system consisting of sensors, radar, cameras and computers is complicated, the development engineers do a good job.
But they're not making as much progress as expected.
The controlling computer is by definition overcautious, when in doubt it decides to capitulate, then the human has to go back to it.
Up until now, its sensory organs have coped better with the complex and difficult-to-predict situations on the road than any computer.
That might be a disappointment technically, but it's also kind of reassuring.
