i totaly, agree. my 4 year old son behaves better,hes suposed to be world. champ, of speedway, not world champ of temper tantrums. 
he needs to  behave, is speedwaya family sport, should he not set a example, like tony r, or any of the other riders who had things go against them, 
well i think, mr crump is the   worst champ we have had for years,just my view tho, the way he behaves, not good for the sports image tho
