In the days before the GoPro, Fangio did this...
 

"These weren’t little GoPros hanging off of the Maestro’s Lancia. Each of these cameras had to be loaded with film, started up, and run a few laps. Then they had to do it again and again so that you don’t see the giant camera in the other angles. It’s easy to dismiss the complexity of these earlier onboard films when we can easily toss a half-dozen or more digital video cameras on a car at every possible angle. It’s part of what makes early onboard footage so precious."

Back when real men drove F1 cars, in t-shirts and no seatbelts!
