I think people imagine what it's like to drive their road car at road speeds (or even fast road speeds), and then multiply the feeling by 4 or whatever to know what driving an F1 car must be like.
But race cars are actually not like that at all. They don't have wallowy bodyroll, or mushy brake pedals, or woolly steering, or uncomfortable seats or nasty seating positions etc etc. They are designed quite carefully to be good at racing. Hence they have direct steering with 1000 times more feedback than the finest road car on sale today - a Caterham is positively rubbery in comparison. You'd struggle to move a brake pedal. The seats are made to suit one driver, and hence are fantastically comfortable even for long periods (I could sleep in mine quite easily).
You get in a race car and it fits like a glove. Driving them at all is easy (although not stalling is a bit of a challenge at low speeds). Driving them at 90% of [decent club level
] the pace is so easy even your grandma could do it. Driving at 95% is barely a challenge. It's only that last few percent that is difficult.
At Hungary Alguersuari was berated for being 3 tenths slower than his team mate. But he'd never gone round a corner in the car until that day. Admittedly he's quite a talent, but still. G-forces aside anyone on this forum could probably get within 5 seconds of the pace in an F1 car within 10 laps. Even Hammond would have managed it if he hadn't been driving on the Stowe circuit at Silverstone which is only good for slow sports like cycling or go-karts.
Racing cars are, quite simply, easy to drive. And I say that as a talentless example.
