Because apparently McLaren’s last teaser video didn’t have enough Back to the Future references in it, they’ve gone and made a brand new one.
Here’s Jenson Button and Fernando Alonso awkwardly acting out a spoof version of the film, where they’re trying to reach 88mph in a McLaren 650S (shouldn’t be too hard) to fast-forward to the Australian Grand Prix, something every F1 fan is trying to do right now.

So the acting is bad and it’s a bit cheesy but massive kudos to McLaren for doing something fun and original!
