I’ve just started getting this, too, ever since watchOS 10.1. I get it nearly every day on my way to work. I’m using the same sport loop band, driving the same route and using the same watch. I did upgrade to the iPhone 15 Pro, but it didn’t happen until 17.1 and 10.1 came out. Now it is daily. This not a genuine warning, it is some kind of bug.
