Why not have the Drag Reduction System (DRS)
Sounds good - I like the idea of it being a button on the main screen that only becomes available occasionally. I could limit the availability of them.
Could be a chance to see the cars from a different perspective too - cockpit view would be nice full off the rear wing & diffuser of the guy in front.
Could be done similar to the "pass the backmarkers" challenge, except you follow one car that is changing directions fairly constantly. Could be activated via a "DRS" button on the main screen that is only active (X) amount of times per race, and only when you are within 1 second of the car ahead.
The main difference with this challenge and the backmarkers is that catching up would be much more difficult and if possible, not always successful.
I think a limit on how many times you can use it may be needed to keep from using it at every opportunity and taking the "management" aspect out of the game.
Sounds great - how do you think we could make use of it? Perhaps with a challenge?
