What I find shocking is that there were some posters here, not many though, but a couple, who put the blame on driving error.
In the first place it is tasteless to remark this after a driver just dodged death but most of all: it is completely irrelevant.
It's not completely irrelevant. The most important aspect of safety is driver discipline. If that goes, then the only safe thing to do is ban the sport.
In this case, one factor is that we have a driver with an appalling record of maltreating other drivers on the track, darting right across with no concern as to who might be there already.
It may have been a mechanical issue, he may have looked in the mirrors and not seen anything (which would make the size and angle of the mirrors a safety issue). But discussing whether the root cause was a driver error is just as valid as discussing whether it was bad track design, debris, logical consequence of traffic, whatever.
And the debate is not just about the driving; it is about the standard of discipline. Look at the 2018 USGP, when Grosjean smashed Leclerc out of the race. He was on 9 penalty points. The stewards should have given him 3 points and therefore a ban; they gave him 1. So there is an element of enabling because the FIA doesn't have the testicular fortitude to hold drivers responsible.
You may disagree, of course, but driver error is a valid discussion point.
