Yeah....Ocon hit Stroll or Stroll hit Ocon (whatever)...but Stroll lost a part of his front wing so had to pit for a new wing.
I look at Gasly's retirement and can't but wonder if the cars aren't too smart for their own good. It would be a shame if the issue was a sensor and not a catastrophic fault. It has to be absolutely gutting for the driver to retire a car that is going well.
