I think they do speed the film up a bit on some of the test drives but a very good programme all the same, and Alan De cadenet is very knowledgeable on the subject.
Watched a few of these before and they are pretty good. I watched the Lotus one tonight. I did notice one small error by De Cadanet. He stated that Jim Clark died during practice for the Hockenhein F2 race. he actually died during the race.
