Seen it before and its a thoroughly good watch! Amazing what drivers went through in those days (not just in F1).
Just watched Senna tonight and it still amazes me that it took his death to really make the regulators buck their ideas up to the levels you see nowadays when you consider how poor driver and spectator safety was in the bad old days. Saying that, most race cars are so safe now that the skill has gone out of a lot of race series since the drivers who dont pay for their own cars have zero fear of the consequences of their bumper car tactics. Touring cars in particular is a particularly good example of some incredibly poor driving standards and its getting to the point where they are due a particularly nasty accident if the regulators carry on letting the drivers act in the manner they do!
