I think the number of bodies involved actually reduces the efficiency, in cases like this: With 16-20 people moving around, it's hard to notice one guy flailing his arms to signify "wait! the air gun jammed" or "no, no, no; the wheel nut became cross-threaded".
Indeed, that was one point Gary Anderson made. With all those people the difference between a hand in the air to signify it's done and an arm in the air saying "Hey, wait!" are hard to distinguish, again especially when the desire to be fast is the key for all teams.
Until it impacts every team, they're going to value four more tire-changers to gain six seconds per race, per the track. After all, some average mechanic's salary of $40k-60k (guessing) is far cheaper than spending millions on some carbon-fiber/aerodynamic doodad that will be obsolete or copied in six months. In an odd way, this is temporary cost-cutting for teams. Moar peoples!
Well this is true but it would only take the FIA to grow a set of balls and introduce some new rules. They shouldn't be waiting for something to happen again before they do something about the cause of the injury, this is far from the first time we've had an incident like this.
(This should really be its own topic, in my opinion; while it did occur in this thread's race, it's been a part of the sport for the past two seasons.)
I would agree.
