There are plenty of other situations where the inability to drive could be life-threatening: in a snow storm, on a dessert road, on a highway at night, etc. The unintended consequences of this could easily outweigh its benefit without even factoring in the privacy issues.
This algorithm is going to have speed,acceleration, traction, steering vs direction as some of the inputs. A good rainstorm or snowstorm is going to tough to differentiate from drunk or high driving. Those aren't edge cases.
And how long then will the car decide you need a time out? 5 mins? 1 hiur? 4 hours?
There is no way this doesn't get pushed back from a 2026 implementation anyway. You can't just drop this in when those model year cars are almost fully designed by now
The comment you're replying to was a reply about weather requiring you to drive not bad weather resulting in drunk-like driving. You're making an unrelated argument.
Also it's perfectly possible to drive safely in severe weather. You shouldn't be swerving or driving erratically in bad weather either. If sight is limited, you're supposed to use hazard lights or (if it's due to severe fog) fog lights to alert other traffic to your presence and drive very carefully and slowly. If the road is extremely slippery you should use season-appropriate tires or snow chains if appropriate and otherwise drive carefully and slowly.
Those are very different patterns of behavior from the dangerous and reckless driving the law is clearly concerning. The pot head carefully going 20 because it feels like going 60 is clearly not the target for this. The drunk swerving into oncoming traffic because the alcohol is elevating their confidence while tanking their reaction time and fine motor skills very much is.
