Apple Watch ghost activity

Simply put: the Apple Watch whilst driving collects many minutes, even hours whilst on long drives.

I’m an HGV lorry driver.

I presumed it was caused by vibrations, someone clarified this, and my post has been deleted.

you would think Apple could tell the difference in actually exercising or sitting in a truck at 50-56mph for many hours? Can’t be that difficult for Apple to realise I’m not exercising with a heart rate of 50-60bpm whilst travelling long distance?
