About the floor damage from hitting the bollard conversation in the comments, Red Bull has released a statement: saying there was floor damage to Verstappen's Car from hitting the bollard. While Max has been saying he didn't felt any difference in pace.
Horner:
Speaking afterwards, Red Bull team principal Christian Horner said: “I don't think we had a great balance all weekend. Obviously, he hit the bollard around lap 20 and that has actually done quite a lot of damage to the underside of the car, so we will have to look at exactly what the effect of that was. "It is a reasonable amount of the area around the left rear floor. There is a reasonable amount that's missing and you can see it awfully flexing as well, so it certainly wouldn't be helping."
Verstappen:
Asked specifically though about Horner’s suggestions of his pace drop being down to damage, Verstappen replied: “It didn't feel different, so I don't know. Maybe it was already damaged. I don't know. I mean I hit that thing and then my pace was the same so I didn't really know if there was damage.”
Please watch and point out where the bollard could even have touched the floor when it was in fact flung up: https://www.youtube.com/watch?v=ORpCycDf-7Y
Again, I'm terribly sorry for posting that link. I didn't mean to offend anyone, nor did I realize the burden of proof was on me.
I suppose Max could've been lying, or the team lied to him, or the Race Just made the entire thing up.
If I had to guess I'd say it wasn't the impact with the bollard itself that caused the damage, but you seem to be well versed in these things so I'll trust your judgement.
I'm not offended. Why would I be? I'm just pointing out that the bollard wasn't lodged between the car floor and the track surface at all. Wing damage: Maybe (but the team saw nothing on telemetry and Max later said to the press that the car didn't feel any different and apparently the lap times were not much different). Floor damage from the bollard: No way.
There has been some confusion about the floor damage, apparently even max was confused by Red Bull saying that there was floor damage as he didn't felt much difference in the car.

Oh, so did you personally inspect the bollard to check whether it didn't break into several pieces from the impact to rule out any possibility that a fragment did in fact went under the car even though the lergest piece of the bollard didn't?
It's pretty clear at 0:31, well as clear as that blurry mess can be. The back left of the car slams on the bollard fixture (or whatever that ground connector is called). At a higher resolution if you look at the body in front of the back left wheel you can literally see the fixture rip off a part of the body. Hard to say if it count as a hole in the floor, but it's pretty clear the car/floor was damaged.
