So max has now been told what he can and can not do.
"No action will be taken against Verstappen for what he did in Japan, but it is likely he will have been told explicitly where the FIA draws the line between what is and is not acceptable"

If true I think that's fair. Lets see what he does at the next race.
That's quite sensible to be fair especially as Hamilton wasn't particularly interested in pursuing it anyway. Maybe this is the line in the sand for his future defences. (I can't see him changing if I'm honest.)
