Good? Well, not horrible, but they have been losing about 1second to Ferrari, Redbull and Mclaren all the time. 3,6 is good stop for lotus, when redbulls can do 2,4 at best and will all the time keep stoppin under 3. Four ****ing tires at 2,4 seconds being changed, that's unbelievable fast.
Great to see this new system without refueling is making stops actually a skill competition of tire changers. With refueling they allways had enough time and it was all about amount of the fuel and no competition what so ever, now theres competition.
Most of the complaint was actually about Karthikeyan. Vettel had enough of a lead to keep Hamilton from overtaking, but suddenly Hamilton was right behind him going into the DRS-zone. That was as automatic as overtaking can get. Karthikeyan didn't leave any place for Vettel to overtake, which caused Hamilton to close in on him.
