Restarting a race is bloody time consuming, for both riders and organisors.
The actions of the inconsiderate few cause enormous headaches for everyone involved.
Hence jumpstarts are a pain in the arse and selfish. Offenders should be put at the back of the grid or barred from the event.
It's made even worse when organisors let some get away with it with impunity. No names no pack drill.

yeah there are some race organisers who do seem to allow jump starting to go on and do nothing about it
worst case i've ever seen was at a race our bikes were on the 1st and 2nd row and the 2nd and 3rd row jump started by a whole row cos the starter was hesitant with the flag so rather than red flagging it and starting again they just carried on with half the grid jump started and the other half wondering what the fuck had happened.
When i asked why they hadn't called a restart i was told that they had tried that before and everyone crashed so they dont bother now, which kind of makes a mockery of having a starter really, might aswell just go when ya feel like it
there does seem to be instances of some riders are more equal than others and rules only apply to those less equal
hey ho thats racing i suppose
