I'm pretty sure theres no requirement to wait for it to drop to low idle before you drive.
Probably not, but if taking off on fast idle, backing out of the garage, or whatever, have to ride the brakes harder. Usually, it drops from fast to slow quickly, like ... 60 seconds. By the time I get my seat belt buckled and radio set, it's usually dropped low.
The important thing with idle, and my dad always said this (with gasoline engines), is to run the engine just long enough the oil circulates to the top of the engine, as it drains down when the engine is shut off. And that takes only a couple seconds to happen. Basically, been following his advise ever since. The only reason to run a longer idle is to warm up the passenger area or defrost windows in my opinion.
My high idle comes down as soon as I touch the brake pedal.
Same here. I wonder if they are setting it manually. One minute to come off high idle after hitting the brake or putting it in gear is an eternity.
Edit. I think I misread what he was doing. I think he meant it goes directly to high idle on a cold start and comes off it within a minute. It would then go back to high idle if left to just sit there I assume.
