With no problem weather and given perfect reliability teams have 15 days of testing available.
Tyres (all compounds) and areo setting (highest to lowest down-force settings) and all possible combination's thereof take a huge chunk of that testing and simply must be completed.
How many of the 15 days are left to test your innovations and theories. And if you have more than one? And given you will want to tweak and adjust. If you have an off or a failure?
The testing ban is moronic. What's worse, it acutally punishes teams for even trying more than one major innovation. A team with no innovations who just copies gets 15 days to test in the preseason. A team with multiple innovations gets ...... 15 days ... ludicrous. Essentially teams are punished for being innovative.
Additional testing in the short term would benefit the new teams, but in the long term would greatly benefit the large teams. Regardless, the complete ban is hurting the sport. At the very least they need to extend the pre-season testing or add a Thursday testing day onto a couple of race weekends during the early part of the season. With 20 races on the calendar there are less and less windows of opportunity, unless they open up something in August.
my view is that the fia are trying to cut cost, make the sport more efficent, in times where money is hard to find, im sure that they would allow in season testing if it were a time where there was plenty of money to spend
and back to the point of the thread, since ive been following formula1, this is the most radical mclaren ive seen
