Bring back grooved tyres?

I know I`m a dinosaur and memory may be past it`s best but I don`t recall 70s F1 cars, or 80s ground effect cars having anything like the problems current F1 cars have when they are in the wake of another car. Who can forget Nikki on the gearbox of james`s Hesketh for 35 laps at Zandvoort or James chasing Nikki at Brands in 76. If you look at Webber following Grosjean in Austin only a couple of weeks ago, he had clearly the faster car and yet through the fast sweepers was completely unable to stay with the Lotus. Whichever part of the aero packages we point our fingers at, the turbulence in the wake of modern F1 cars has had a detrimental effect on racing for too long. DRS to me is a pathetic and artificial method of manufacturing an overtaking manoeuver.Could you imagine telling Ayrton, if the guy gets within a second of you all he has to do is press a button and he sails past? Racing it aint!

In the 70s aero was at its infancy, the turbulent wake not as detrimental. I remember Jody Scheckter or Emmo mentioning being affected by following another car at Interlagos one year.

Medium-high speed corners are generally the worst for following a car because that's when you need downforce the most.

Even a flat winged Indycar creates significant turbulent wake so hardly a problem unique to F1.
