Hi, It seems as if a car that is 0.8 seconds behind another can overtake in the DRS Zone. i.e. gaining that time.
Then why don't the teams do a 'Two-Up' to gain that 0.8 seconds every lap by taking it in turns to
use the DRS Zone.? It works for cycle teams, so why not in F1.
Because the car behind is only gaining the deficit to the car in front. To gain an advantage, the car behind would need to gain the gap to the car in front PLUS a bit more in time purely from the use of DRS.
In a front runner on a lesser car, this would be easy. As they would just breeze by.
HOWEVER, against someone in an identical car, the difference in speed would not be enough for the tailing car to easily overtake the car in front without the car in front compromising their lap time. This would mean that overall, as a pair the two drivers would be slower if they kept swapping places in the DRS zone, as it would take longer for the 2nd car to cross the start/finish line in front of his team-mate from when his team-mate started that lap - than it would if his team mate just drove as fast a lap as possible.
IE - Lewis/Jenson example
Lewis leading, Jenson following.
Lewis driving as fast as he can does a 1min40 lap.
Using the DRS trick, it might take Jenson 1min41 to cross the line from when Lewis started the lap. Meaning they'd have lost 1sec in ultimate lap pace... (at least because Jenson would have to come from a min of 0.5secs behind and be a min of 0.5secs ahead
