Been watching some archives on F1TV, 1970 to 75 so far. We all complain here about no close racing, well back in the day it was that x 10. One race the second guy was really close to the pole sitter, half a second. They often stretched out like browns cows. Id say the cause was few restrictions, so you would often get poor cars and unreal cars, the rest scattered in the middle. Tyres? Two brands, one was better in the dry one was much better in the wet, my god!
