Displaying DRS/KERS zones

The game would be a lot more interesting to play if the developers add information about the DRS/KERS zones in each circuit just like weather and circuit data. It would make way for new and innovative strategies by players. What do you guys think ?

I agree but there're many managers has already suggested the same thing before but still get ignored.
But KERS doesn't have any selected zones in the tracks.

Neither the detection zone nor the DRS zone are indicated. It is a pity that they do not give answers to a request that many managers have made.

I don't think there is a detection zone. I may be wrong but it appears to be calculated at the point of entering the zone. I agree that it would be nice if the zone was more obviously visible 

Correct, you have to be within a second once the DRS zone starts, so essentially the detection and starting point for DRS are the same. 

I suggested this a while ago and it got approved, guess it’s just a wait to see when they actually put it in the game
