Hamilton wanted the pitstop as soon as he saw the crash from the tunnel and he was complaining about it during and after the race, he wanted a straight undercut on rosberg to try to get ahead and didnt want to stack up in the pitlane
Lewis is wrong in more ways than one, of course his evil plan to undercut Rosberg is incorrect, it goes against the established idea that the lead driver gets priority, but even if mercedes gave him that pitstop then he would have lost alot of time compared to people around him
Lets break it down, Rosberg continues on as Hamilton pits behind him, Raikkonen is 12s behind and he continues on
Hamilton exits the pitane in 5th place, around 25 seconds behind Rosberg who is at Mirabeau, 13 seconds behind Raikkonen and 12 behind Ricciardo
So now the safety car comes out 10 seconds later as Hamilton is on his way up the hill, he and everyone else immediately needs to slow down to a delta time, almost safety car pace, at this time Kimi is 13 seconds ahead lets say around Mirabeau but because Hamilton now has to crawl around to that part of the track it now takes him much longer to get there (I did a comparison of how long it takes drivers to exit the tunnel and reach tabac in normal conditions and while slowed to a delta time and its just less than double) kimi now has a much larger lead over lewis and might even exit the pits ahead of him
In conclusion lewis isnt smart and should leave the tactics to others
