I do understand the 'Let em race' attitude and crashes will happen if we go racing. For example noone is discussing stroll crash last weekend in that way, like that was a heavy impact and it wasnt his fault what can be done about punctures. No, we just accept punctures happen and that can lead to a big crash.
However the startline crash was so silly, but could have had much more serious outcome and could have been avoided really easily if the pack was properly bunched up. The rules around the restart should be tweaked to avoid a startline crash in the future rather than wholesale new ideas like a 1 lap VSC period to reestablish gaps in the field.
But if we want them to be racing, why are we keen to keep them apart?
Really, scary as that crash looked there are dozens of similar or worse every year across the very top levels (F1, F2, IndyCar, SuperFormula) and, on average, few to no injuries.
When a driver or two would die every couple of years (the golden days most are misty eyed about) the queue of willing racers was infinitely in excess of capacity.
I just watched a man jump out of a plane, parachuteless, in the assumption that he'd find a net to land in.
Sooner or later you have to give the recklessness of youth/old enough to know betterhood space to do what it will - and the crash on Sunday is what happens when lots of people who've bet their lives on making it in a sport know that finishing 10th is an achievement but finishing where they are is worthless.
Nothing other than keeping them apart will protect them - and if we keep the apart, what exactly are we paying to watch?
