Specifically on the reversing thing, it was a bit silly, but it's one of those rules that they couldn't not reprimand him cuz reversing in the pit is prohibited (or something like that).
While for Max, it was a very dangerous move, but I think the teams and drivers have been lobbying the FIA to let them race... which they did... barely any investigations this weekend. I was sure ALO vs Hulk in the pit was gonna trigger something, but it didn't. For sure they're gonna talk about it this Friday during the driver's briefing in Monza. A late move like that at a high-speed section of the track can't be deemed acceptable.
