It's really just a matter of experience, and believe me driving on the road is NOT like driving on the track or playing a video game
As multiple people have pointed out before me operating a car is easy but that's not really driving. Driving is going around rather than over/under or through all the other idiots on the road.
One of the most important things is leaving enough space between you and another road user to avoid them if/when they do something terminally stupid. However this is a skill that requires a little practice, since if you drive "cautiously" and appear to be hanging back leaving too large a gap then some clown who does not consider paying attention to other road users a relevent skill will come along and put a car or a white van in it.
That's the balance that comes with time :- leave
enough space, but not too much, and
enough space is determined by the car you're driving, the speed you're travelling at, how alert you're feeling, and how many other people are around you.
That's why you never actually
stop learning to drive, no matter how long you've been doing it for.
Good luck with it, I passed long before theory tests, or parallel parking were considered necessary, [my examiner asked me to identify 3 road signs and tell him the highway code quoted stopping distance from 70 and that was it]. I do remember how hard it was to reverse around a corner the first I tried it, but other than that it was easier and a damn sight cheaper to get a full licence way back in 1988.
