i like DRS. but i think its too overpowered. The art of defense is pretty much dead in F1, unless by a sheer coiincidence the track conditions all line up, the two cars battling are on similar tyre wear, the defending car has good top speed, and all the stars align, then you get some kind of ability to defend - or you have to max verstappen it.
however - turbulence was obviously an unintended consequence of the aero era, completely out of the drivers control, and this difficulty of running close to a car infront neutralising a major aspect of motor racing..... and sticking on degradable pirelli tyres didn't help matters.
So why can't they make a DRS which uses GPS or some kind of radar that can detect the speed differential to the car infront - and if its over say, I don't know, 10kph, it automatically shuts the flap again. So it's powerful enough to overcome the wake and allow the attacking car to get into the slipstream out of the corner and launch an attack, but not so effective that the he can continue using that massive speed difference and simply drive past the car infront like he's on the motorway.
then you wouldn't have to worry about length of DRS zones, placement of the zones, where the DRS line should be placed, etc..etc...it wouldn't matter as much as it does now.
and the second condition would be - once the car is within say 2 metres of the car infront, having used the DRS to overcome the turbulence, the flap also shuts.
i'm not sure how it would work, either using location or radar i guess... but could this be a simple solution and implemented easily? would it not fix pretty much.......the single biggest problem with F1?
