This happens in many categories, I think drivers need to have a button on the steering wheel that will set off an alarm in the starters tower and trackside led lights if they stall on the grid.
As it happened live I thought wtf is that board the starter is holding out, the 5 second board? but the lights are green, then it was just a fireball, so the marshalls were all onto it but the drivers have tunnel vision at that point in time.
