Every time I get in the car the watch says I take a few dozen steps especially during longer drives.
I have two cars and on one of them my iPhone connects via Bluetooth to stream music so I would assume the watch knows I’m driving. On my second car I don’t connect my iPhone at all and use CDs to listen to music, but nevertheless on both cars the watch and activity app on my iPhone both add steps during my drive. I’ve even strummed my hand during guitar solos at a red light and then check that my watch has added steps.
