IMO the race was worth the wait, good fun. Nice to see Sato going so well, rather wish the race could have gone the distance on laps to see what he could have done without having to coast the whole time saving fuel, but then the drying track might have done him in. I'm sure they expected at least another caution(as did I).
Viso for his part after the race claimed(honestly or not) he was looking for water to cool his tires... probably conveniently chose where to look for water
. I didn't see him to be doing anything particularly rude, but he should know the rules by now, and he doesn't exactly have a stellar reputation.
I do tend to agree that it's a very silly rule, but it's probably responsible for a lot of the passing that does happen. I guess it's a bit like IndyCar's version of DRS, providing an unfair advantage to the following car to improve the show. Amazing that with such a rule they still find it so hard to pass at many tracks.
