That great old 1970s footage reminded me that F1 back then was more fun to watchmostly because you could actually see things happening. Current cars are so quick that as a spectator you have no chance to physically see anything but what looks like a blur on rails. So it's useful to see the bad to appreciate the good.
Have a look at how quickly Vitaly Petrov's car snaps from under him. Braking events average about 1 second, is it any wonder there is no passing? What is surprising is that there are not more errors with such a small window to hit lap after lap.
