That's the downside of this sport compared to others.
If you're a long distance runner, your ability to win is purely on your talent and how much practice you've put in. With motorsports, you can be a great driver but it's out of your control if your machine messes up.
And indeed how good your machine is! That's why we'd always like to see certain drivers in better cars. I'd loved to have seen hulkenburg or Sainz in a better car just to see what they could do.
