At 1.28 that looks pretty real. I am assuming / hoping its a camera on dolly track and someone tugs it on a robe at the last second. I think the footage is speeded up.

2.40  I think thats Hitchcock’s STRANGERS ON A TRAIN

Strangers on a Train (film)

I 3.22 we see the words “dan marruffo ”

I googled “dan marruffo  race car movie”

and found :

The Dan Marruffo footage is 2 minutes in….  I suppose thats documentary / newsreel footage of a real race.

 

I’ll keep searching and keep you posted.
