One thing that surprised me was that with the telemetry still out cold, they don’t seem to be able to police the DRS activation, or simply didn’t bother.
For example, Alonso activated his DRS actually way before the activation line on the pit straight on Lap 3. In fact his DRS deployment was a 2011/2012-style qualifying deployment where he basically mashed KERS and DRS as soon as he was full throttle:
Meanwhile, you can see that he hasn’t quite passed the DRS marker board/DRS line to signify the DRS zone (black thingamabob to the left):
Rosberg, however, activates his DRS properly, at the proper timing:
Worth noting that Alonso’s DRS was still capable of closing at this time, as seen here, before and after the DRS zone:
I picked up on it during the race, but was surprised to see no one else mention it yet (or if it has been mentioned – I missed it)
