Kyle Busch likes to live on the edge, which usually means driving his No. 18 Toyota Camry on the limit of grip. When he’s at home, though, it means standing on the literal edge of a metal frame near a 50 cubic-centimeter motor.

The ever-controversial Joe Gibbs Racing driver tweeted a video Monday of him and his son, Brexton, taking a go-kart for a spin. Busch clearly doesn’t think his son is ready to take the kart out alone, and he’s probably right, as Brexton seems to have trouble keeping his eyes on the road.

Hey, no one’s ever been named dad of the year for being a stick in the mud. But considering Busch was the 2015 Monster Energy NASCAR Cup Series champion, you’d expect him to be a bit more concerned about messing up Brexton’s weight distribution.
