I get the impression at the races that officials are loathe to come down too hard on drivers for fear of them leaving an already depleted field. I don’t necessarily agree with that strategy but I think it’s a real problem. More penalties will solve our problems way before collapsible kart parts will.
Disciplining drivers (and Dads, tuners etc.) is not unlike raising kids. Let them know what you expect and be willing to punish them if they don’t meet those expectations. Idle threats get you no where and following through changes behavior.
