i learned in my early 20's (and was petrified) - my bf's mum learned in her 30's, my aunty learned in her late 40's... (all driving cars with a manual gearbox- none of that automatic silliness
you can learn any time, and be a decent driver, as long as you have a degree of common sense, the ability to make simple decisions decisively, some kind of multi-tasking ability (like the ability to turn your head and not have your whole body follow it -that one took me a while- whenever i looked left i steered left as well for ages
-, or to move something an inch or so while paying more visual attention to something else- most people can learn that- if you can walk while talking on a phone, type while looking at a screen, or similar, you're already there!) the ability to practice, and retain information and skills for more than 10 minutes, and um... a degree of common sense.
there is quite a lot of timing and spacial awareness stuff going on in a car when you're driving, but most of it becomes fully automatic after you've done it a bajillion times, just like other things you do every day do (like managing to not walk into walls constantly, knowing whether you can reach something before you reach for it- stuff you learn as a baby- etc).
just have confidence in your abilities, and plug away at it til you've got it down like a pro. some people take longer than others to become profficient drivers, but that doesn't make them better or worse in the end. it took me 4 goes to be confident enough to pass my test, and i've hit way
less things than my little brother who passed first go.
