F1 Battery and DRS strategy

for a few days now I begun to wonder, can't a team use the DRS and the batteries to gain speed on the straights? let's say car nr.1 goes in front and uses the battery on the straights and car nr.2 uses DRS to follow at a high speed. Battery drains out, car nr.2 with a full battery goes in front and car nr.1 uses DRS behind. Couldn't you do this to gain laptimes?

It may be possible with a lot of synchronisation but I doubt it'd gain you much.

They did that from 2009-2013. The energy stored in the KERS system could be deployed at any point during the lap.

You could use it to attack/defend a position, or apply the 6.33 seconds you had strategically a few squirts at a time around the circuit for a faster laps.

Beginning in 2014, ERS is magically computerfied to be applied at all times, especially during times of lag (it can spool up the turbo to build boost while in lag) It's mapped, and controlled by one of the 50 knobs on the wheel.

F1 drivers no longer directly control the deployment of electric power as they did in 2013 and before. The amount of power they can recover and use throughout a lap is also significantly increased from 2013, when they had ~7 seconds of full power to deploy. These days there is enough capacity in the batteries to deploy full power for around 33sec/lap, IIRC, and the car's computers now control when it is used. The car deploys electric power strategically to add torque to the combustion engine at lower RPMs to fill in for turbo lag, to spin up the turbo itself and to add to top end power.

As for DRS, there is a detection point before each DRS zone that allows only carscars within one second behind another to use the system. Trading places on a straight wouldn't then allow both cars to use it.

Aha, I see now... I thought the battery was still driver controlled
