At LSC Lodon, track calls have always been severely restricted. 
Track calls ruin the flow of the race and are only permitted when a car is stranded under the bridge or hits the floor in the other hard -to-reach parts of the track. The track is well designed so Offs requiring track calls are very very rare..

Drivers learn to be patient, marshals are quick but clinical. No cars are slammed back on the track after an off. 

Certainly, drivers handling each others cars during a race night must be minimised in current times.
