Button, who shared the footage, has called for the racer and his father, who is believed to have been involved in the attack, to be banned from motorsport for life.
“Luca Corberi has just destroyed any chance he had at a racing career after his disgusting behaviour today at the FIA Karting World champs,” wrote the 2009 F1 champion.
“His father owns the circuit and is seen power driving the guy into a wall. Life ban for both of these idiots please.”
IndyCar driver Oliver Askew added: “Disgusting scenes from the CIK World Championships today, no place for that in our sport. Could have been a very scary outcome for the drivers on track and should be a good lesson for young drivers on how not to act.”
Former F1 driver Giedo van der Garde called the incident “truly unacceptable” and joined calls for a lifetime ban.
“I always teach the kids I manage that respect should always be in mind when racing. I’ve been swearing a lot in my car, with my helmet on, but you always should keep your calmness. This is an example of how not to be a driver. Truly unacceptable, should be banned very long.”
The two karting racers involved were disqualified from the event for the collision, though the FIA has yet to comment on Corberi’s behaviour.
