Last night I experienced the Attention Assist alert for the first time since I own the car (a few months in).

It was 2am and I have to admit I wasn't in the best shape to drive (no alcohol, but was exhausted after a long day trip).

Even though I was not as alert as I wanted to be, I was fairly certain that I never drift out my lane during the entire trip. I wasn't speeding nor swaying left and right. The alert happened twice during my 2 hours drive back home.

Does anyone know how the system works? I did have it set to 'sensitive' but I was surprised the car detected my tiredness.

Anyhow, even though we were not in any danger, I was very impressed with this life saving feature. The car will give you a loud 'ding' sound when the alert comes up, and asks if you want it to find you a place to rest.

I don't have sensitive enabled, I have it on normal and it went off twice on the last hour of a 5 hour drive. I suspect it monitors erratic (even slightly erratic) behaviour in all controls plus a timer of some sort. How it does it is less important than it does it and it seems to work.

It seems to work well, it got me when I was tired one night.

Mine made me coffee and dispensed it through an air vent. Cream, no sugar.

There are two settings for this feature:

1) Slightly Dopey mode - this serves Cappucino or Latte. The second,
2) Eyes Wise Shut mode - Double-shot Expresso, intra-veinous.

'Stuttgart Voodoo'. Apparently it monitors over 70 metrics to do so.

The mind boggles - I'd love to see the coding rules for that ..
Item 69 on the sensor list - If driver listens to 'Engelbert Humperdinck's - Greatest Hits' any more than 3 times in a row - deploy the emergency brakes.

If I drive more than 2 hours in a row early in the morning on the speedway without having a break, attention assist beeps after 2 hours. That's the one metric I have experienced consistently
