Hamilton is regarded as one of the most complete drivers on the grid, excelling across a wide range of areas. He has been described as having an aggressive driving style, with a natural aptitude for identifying the limits of the car; Mark Hughes, writing for the official Formula One website, described how Hamilton is "super-hard on the brakes ... but has a fantastic ability to match how quickly the downforce is bleeding off with his modulation of the pressure so that there's no wasted grip but no locked wheels either." Paddy Lowe, previously the engineering director for McLaren, described how Hamilton is comfortable with levels of rear instability that most other drivers would find intolerable. Hamilton has also been praised for his ability to adapt to variances in the car set-up and changing track conditions; throughout his career, he has typically used less fuel than his teammates as a result of his ability to carry momentum through corners despite instability in the car. Pedro de la Rosa, a former test driver for McLaren who worked with Hamilton and Alonso, rated the pair as the best he had seen first hand, stating that they shared a strength in terms of "how much speed they can run into the apex a corner and still have a decent exit speed", highlighting in particular their ability to maintain this speed when their rear tyres have lost grip during a longer stint.
