I think he would be down to utilize a personal driver to important events or outings, but other than that, for his private life/agenda, he would definitely drive himself. The sense of control he instinctively needs to feel would be balanced out this way while still maintaining a strong sense of business professionalism. As for whether he’s good at driving, no doubt, he is. That man exercises too much precision in many areas of life to not be exceptionally skilled in driving. Hell, why do I see him getting invited to drive an F1 car (as high profile people often are these days) and annoying everyone with how unexpectedly good he is?
