I seriously expect them to open up the DRS window within the next few races. As a short term fix it may have merit, but I suspect will introduce as many problems as solutions. The blue flag issue on the other hand is a larger problem. If 2 to 3 seconds worth of turbulence is going to be the rule you can hardly start expecting the rest of the pack to give up that much track position just because the top four are coming around. These guys have races to run as well and while not for podiums, the points battles are critical for their finances.
