There were no safety cars back then. If you look for races of the 80s on YouTube you can see cars parked all over the place and becoming part of the track (especially at Monaco.)
If you look for races in the 70s and early 80s you can see photographers on the grass at the inside of the curves.
And the invasions at Monza when the cars were going back to the pits after the end of the race. This is one of the last ones
