Even if we take your generous interpretation of what he said, is he wrong? It's pretty clear he can still be "fast" in the new car, but it doesn't mean he enjoys driving that way. There's nothing wrong with saying he doesn't enjoy the new regulations. Hamilton and Alonso both have given similar opinions and when the three most decorated drivers tell you it sucks maybe there's some truth here? Maybe the regulations have shifted too much from being fast to being energy efficient.
