Garmin Thinks I'm an Olympian… Even When I'm Just Sitting in a Car

Hi everyone,
I just bought my Garmin Vivoactive 5 three days ago. Today, I was only sitting in my car driving around, and somehow my watch counted over 8000 steps — even congratulating me for exceeding my daily step goal.

I’d like to ask:
 Small blue diamond Is it normal for steps to be counted while driving?
 Small blue diamond Is there any way to improve the step tracking accuracy?

If this keeps up, I might just break the world walking record without even walking Smile
Looking forward to your thoughts — thanks!
