The FIA has invented
a test to determine mirror visibility. This, of course, follows the multitude of innovations the teams have embarked upon lately concerning the humble "driver awareness device". The test involves a driver sitting in the car and reading numbers on pieces of paper displayed by an FIA official 10 m behind the vehicle. Since vibration could be part of the problem, I don't quite see how this exercise offers any kind of a realistic picture of the visibility the driver has.
Mark Webber has expressed satisfaction that the test has now been implemented (I'm guessing in his capacity as a member of the leadership of GPDA). Fisichella, on the other hand (perhaps predictably, since the mirror is an integral part of Renault's unique sidepod construction) stated that the visibility is "fantastic" and "better than last year".

No word yet whether there have been any conclusions or if anyone has been ordered to rethink their construction, as far as was decipherable from the article. Personally, I'm wondering how much the drivers have ever relied on the mirrors ... remembering how a BAR Honda's race engineer, for example, talked Takuma through the start on the team radio. The instructions were so minute, I was left wondering whether he could've driven eyes closed until the first corner.
Well, maybe the "mirror/F1 eyesight test" was merely a cosmetic one. But if changes are forced upon teams that have their mirrors placed at the extremities of their cars, it could have some aero implications.
