The technology of the car-wizard has its limits

Mr. Cavegn, yesterday it came on the A3 in the Canton of Aargau a severe rear-end collision. Modern driver assistance systems could prevent what yet.
it is Clear that the assistance systems have a large mitigation potential. In the case of rear-end collisions, we expect that their frequency can be reduced thanks to an emergency brake assistant in order up to half.

Why not to zero?
assistance systems can always be overridden, ignored or completely turned off. If someone is driving too fast, that can be displayed and, for example, acoustic signals illustrated. At best, automated or partially automated Driving, the assistant would intervention systems always. But we are in Switzerland is still far.

According to police, the accident noticed the lane narrowing from two to one lane late. A wizard would have recognized it?
emergency brake wizard to detect vehicles driving ahead, depending on the System, motorcycles, pedestrians or static obstacles, such as, for example, a lane change signaling. But all technology has its limits. For example, in the case of rain, snow or fog, or dirty Sensors. Specifically, this means that you can never rely on such systems.

do you Recognize this as a Problem that car drivers to rely on technology?
We have no sound data. But there is certainly evidence to suggest. I am thinking here of media reports about accidents with cars that have a faith, Autonomous Driving is already possible.

in The accident on the A3, the driver of the blocked track is moved to the other lane and pushed there car to a car in a truck. Can align the lane assist here, what?
If someone is fast on the road and something Unexpected happens, then it may be that the driver is startled and technical alerts is not responding. Even if the wizard warns him in time.

How far ahead you can see a vehicle "wizard"?
it depends on The assistance system and the technology used. This is a hand made with cameras. Other systems work with Radar. But also the type and the number of Sensors plays a role.

Why technical assistance cannot be designed simply so that you can intervene in critical situations and the Oversteer, the driver lock?
The legal situation is not so. All of the assistance systems have to be set by law so that they can always be overridden.

Great it would be if I was emerging as a potential victim of an accident a Crash-preventer-wizard would have.
What is already there, is an automatic activation of the brakes when an impending collision: For example, if a car is in a column and in the back of the vehicle with high speed is approaching, then automatically, the brake is applied. Of course, the Impact of the collision is reduced, and the biomechanical load of the occupant is reduced. And it is planned that cars will warn in the future, each other of hazards.

this accident Wouldn't have happened with a Tesla, the part is Autonomous on the road?
I do not go out. Even if advertising and Marketing suggest something else. And like you said, at Least fully Autonomous Driving is in Switzerland and also in Europe are not yet possible.

Even if a vehicle assistant can avoid accidents entirely, it can help to reduce the number. When will this technical assistance is actually mandatory?
In the EU must be equipped delivered from the middle of 2022, all new cars with vehicle wizard. We are talking here of various technical AIDS such as emergency brake, lane keeping and speed wizard. Switzerland will take over probably.

And then you expect significantly less accidents?
a Rough estimate, we assume that the accident risk is reduced by up to half, if all of the currently available systems would be consistently incorporated.
