00:00:02,418 --> 00:00:08,998
Four in the afternoon. Cars stream across the viaduct, the newest with a system on board.

2
00:00:10,220 --> 00:00:20,922
Since July 2024 every new car registered in Switzerland and the EU must warn a driver who is nodding off.

3
00:00:21,662 --> 00:00:27,540
The sleepiness scale is the same for every car: the warning fires at eight out of nine.

4
00:00:29,720 --> 00:00:35,112
But the system warns once sleepiness has already started. It doesn't see it coming.

5
00:00:36,519 --> 00:00:43,878
It is a last safety net, not a green light. What still matters is how much you slept.

6
00:00:44,622 --> 00:00:48,822
The warning comes afterwards. The choice is made before the drive.
