I thought the finish was exciting but I was surprised to hear it dubbed "unbelievable" and "the best ever" like some people did on TV.. (I actually think Ben Edwards is in love with Verstappen. No wonder whatever VER does is simply great. Haha.)
I have a suspicion that RedBull gambled setupwise on the declining (track) temperatures towards the end of the race (however I did not check if [even...] Gasly improved his laptimes proportionally. So it's just a pure guess based on pure gut feeling and might be bunk). That said: even if it were so, it would still be a strong finish for Verstappen.
But let's not forget he had much fresher tyres at the end (were Vettel's even fresher though? sry, if I make false claims. I only watched with like 80% attention, at the end maybe 90%...
)
As for "the" pass. Well very, very, very brief put: I'm afraid we have to get used to it, that pushing a car off track is the norm nowadays. No, I'm not a friend of penalties and cars touching and bouncing eachother is great but that's not even the point. The point is: what is the message to the drivers? Concerning.... unless of course you
intend to go towards the direction of Formula-E which is semi-autoscooter thanks to the wheel-protections.
As for DRS: it's way too effective. I don't even know why they bother showing replays of DRS-passes. Haha.
Let's put the option of removing DRS aside for the moment.
DRS should automatically close as soon as the car behind leaves the slip stream (I would think that's technically even possible by utilizing the data from all the venturi's on each car... pressure goes up - DRS closes - both drivers need to solve it back in the braking zone again)
(EDIT: i think nowadays GPS signaling would be enough. The point is, as soon as a car goes next to another)
