Easier when the person in front keeps making mistakes. Also Bottas was on softs and Vettel on med for the last stint. Looking at the pace Kimi showed in the final stint, it would have certainly made Bottas difficult to pass for Vettel.
here are the explanations from vettel as to why he was stuck behind bottas:from ferrari.com
"Towards the end, I was struggling to get past in the fight against the Williams. When it was important to be quick, I always seemed to get stuck in traffic, and thus damaged my tyres"
I was trying to push, and when you’re following another car you obviously lose a lot of downforce. With hindsight, it was probably more than I expected.
here is jamesallenonf1 explaining why vettel was passed after undercutting rosberg:
In order to make the undercut you have to push the tyres very hard on the opening lap, which overheats them and causes problems later in the stint and you also deplete the ERS battery fully. This leaves you vulnerable on the following lap, when the car you’ve just undercut now has the new tyre advantage and he’s got a full ERS battery to deploy on the main straight.This scenario is precisely what happened on Lap 15, when Rosberg re-passed Vettel as they came down the straight, with Hamilton exiting the pits ahead. That overtake was all about Rosberg having full ERS power to deploy and Vettel still recuperating from his fast out lap.
and here is jamesallenonf1 talking about the ferrari and merc PUs and what he expects in the near future all from jamesallenonf1.com:
One of the reasons why the Ferrari is such a strong race car is because it has an aggressive engine mode, with a strong battery and an efficient compressor, which it is able to use all race long, whereas Mercedes has to dip into a more conservative mode at times during races. This gives Ferrari a chance and means that over a race distance there is now little to choose between the two power units. Qualifying is still Mercedes’ forte, which gives it a track position and thus a strategic headstart. But if Ferrari keeps up the current relative development rate then we could have a championship fight on our hands.
