snowy I did acknowledge that an F1 driver is better aware of his car than the rest of us, but not to the point where you think. If you check pit stops you will see that in all cases there are mechanics sat at the points where they want the front wheels to stop with a visible marker on their arm so the driver can use the top of the wheel to gauge where to stop, nothing mythical about it.
The rear wheel on an F1 car is not actually as big as it would appear, especially not when turning through a 90 degree hairpin and under control of someone else where you don't know where the wheel is going to accelerate or brake or even the line change due to the other drivers actions. You have to remember you are not talking about the whole wheel, just the specific section where end plate can meet side wall of tyre. If Lewis had been a 10th of a second later on the power, turned a few extra degrees into the turn or even managed to carry more speed into the turn than the previous lap by a few mph then Nico was bang out of luck and was putting his car on the dirt at the very least if not taking out his whole front wing and needing an emergency trip to the pits.
Easier to hit if going down the straight at a constant speed without change of direction, and if Nico wanted to cause a puncture then this would be the place to do it, not at a point where he does not know Lewis's actions with regards to brakes, power, steering angle etc.
If Nico intentionally wanted to cause specific damage to another car then doing it at the point he chose to was the hardest thing to do and risked more damage to his car than to Lewis'.
So again I will stick with my opinion that Nico probably chose not to back out of a situation where he knew there was going to be contact, but the resulting puncture was more luck to him than anything else, even if he did wish for it.
