Didn't get of Scott free though, did he?
True, but both Jason and Ash carried on, and JP was chucked to the back of the grid for the next race.
I think - and I can see where the stewards were coming from on this one - that the reason Seb and Charles both got off scott free was that they were out of the race on the spot after that moment of argy-bargy.
Now I don't think they *should* have gotten off scott free, especially since they effectively kiboshed Lance Stroll's race thanks to the debris they left on the circuit. OK, we've been moaning about the stewards all season - the only consistent thing about them is their inconsistency - but IMHO the sporting regs are as much, if not more to blame for the current omnishambles.
I'd prefer to see a touring car style penalty system instead, where you let the cars race, no silly and ineffective time penalties except for clear safety violations e.g. unsafe release from pit stop, but then grid drop penalties are applied for the next race, and / or demotion in the results to behind the driver that was impeded.
