There’s hundreds of snowmobile accidents every year:
Today, snowmobiling has become a popular winter sport enjoyed by more than 2 million people of all ages in North America. However, the modern snowmobile can weigh in excess of 600 pounds and travel at speeds exceeding 90 miles per hour. Each year snowmobile accidents produce approximately 200 deaths and 14,000 injuries. Excess speed, alcohol, driver inexperience, and poor judgment are the leading causes of accidents.
High speed thrill-seeking on a vehicle that you can only practice using a few months every year means a lot of accidents.
