Article 27.5 is about slow driving cars. Verstappen going full throtle of the kemmel straight is definetly not a slow driving car so article 27.5 doesnt apply to this situation.
No, it does not. It is important to notice that it says "or" not "and".
27.5
At no time may a car be driven unnecessarily slowly, erratically or in a manner which could be deemed potentially dangerous to other drivers or any other person. This will apply whether any such car is being driven on the track, the pit entry or the pit lane.
In order to ensure that cars are not driven unnecessarily slowly on in laps during and after the end of qualifying or during reconnaissance laps when the pit exit is opened for the race, drivers must stay below the maximum time set by the FIA between the Safety Car line after the pit exit and Safety Car line before the pit entry. The maximum time will be determined by the race director at each Event after the first day of practice but may be amended later in the Event if deemed necessary. The time will normally be based upon 145% of the best dry P1 or P2 time.
Again, it is "or" not "and". You may not drive unnecessarily slow. You may not drive erratically. You may not drive in a manner which could be deemed potentially dangerous to other drivers or any other person.
The second part, is how they define "unnecessarily slow" when it comes to those specific areas of the race weekend.
About 27.8 it does leave allot open for interpretation. It is and has been legal to run people wide on the exit if u are in front at the apex. This is exactly what Hamilton always does an he too gets away with it. U know why ? Because it is allowed and perfectly legal. When the driver on the inside is in front at the apex he deserves the right to determine his line trough the corner. It is up to the driver behind to concede or run wide.
It is been accepted that the stewards do not bother with such stuff, but it is, in the way the rules are written, illegal to force another driver off the track, which is what they are doing. Also, Verstappen was not in front at apex, he was on the inside, but was not in front. At no point in the rules does it state anything about "inside vs outside" or "racing line" because that is, irrelevant if two cars are side by side. And forcing another driver is not allowed.
Speeding under yellows are not allowed either, but drivers do it, without any penalties, and we do know how that can end up.
I find forcing others off the track being extremely ugly racing, but also very weak racing, if you can't beat them, get them off the track, or spin them...
About the first lap you are probably right. And like i stated before the move in les combes was worthy of a penalty to imo as he failed to make the corner. If he would have made it it would be perfectly legal though.
No matter if he had stayed on the track or not, he forced someone off.
On a sidenote, Perez passed Verstappen off the track, there was no investigation on it. So, somehow they must've thought it was OK. But if it was OK, why was it ok... If it was because Verstappen forced him off anyway, why was never Verstappen investigated, as he did it twice...
The stewarding at Spa was very off. It's almost as if they was so embarrased after the whole Hamilton-Gearbox at the start of the day, that they went to pub and let the automatic system handle the rest. Which is why Nasr got a 5 sec penalty, as that was a computer that registered it, and no "investigation" on it either.
