People are dunking on this, but I think it’s extremely practical. Heart attacks after shoveling snow kill 100s of people in the US per year. Shoveling snow pushes you close to your max heart rate within minutes. And the cold air constricts your blood vessels, causing blood pressure to rise + increase your heart's workload. There’s data that shows heart attack-related hospitalizations increase 16% following 7-8+ inches of snowfall. I had a family member die this way recently. It’s a very serious issue and this type of technology will save many lives.
