In the US I’ve noticed a difference between west coast and the rest of the country. West coast tends to use these circle bandsaws to cut circles into the pavement, everywhere else uses a circular saw to cut rectangles into the pavement. Either way, these are the things you want to be stopped right on top of, especially if you’re on a side street or left turn where you might get skipped if it doesn’t sense you. If you’re on a motorcycle, try to scoot up a bit so a car can be on them. They probably won’t sense a motorcycle.
You triangulate the signal and pass the coordinates to artillery teams.
