It wouldn&#x27;t be any more expensive than walking into someone, with them falling down and breaking their back. Hitting someone with a bicycle can cause serious harm and cost you a lot of money, yet I know one person who owns insurance for riding a bike - 99.9% of people riding bikes don&#x27;t care. I don&#x27;t see why it would be different for this, it&#x27;s slightly faster than walking and slower than riding a bike.
