28. Batman’s son, Batboy, is thirteen. One night, while Batman is playing poker with the Commissioner, Batboy sneaks into the Batcave, stuffs a chaw of chewing tobacco in his cheek, jumps into the Batmobile, and takes off like a bat out of hell. Robin is walking his bike across the street at a crosswalk, and Batboy negligently hits him, ruining the bike and injuring Robin. When Robin sues Batboy for negligence, what standard of care will Batboy be held to? _________________
