So, I've been driving for awhile now. Probably started in.... 1998? Driver's Ed and all that.
And I do ALOT of driving. Sometimes just out of boredom. The only type of area I never enter is urban zones. But anything from country back roads to major interstates, lots of experience.
For someone starting out, there are a few things that I kinda want to mention just to add to the conversation here.
Firstly: No matter what, you *must* be able to keep your eyes on the road at all times, period. There cant be any exceptions to this... not even one. I mean, if you're sitting at a stoplight and you want to look at the console to change the radio station or something, that's one thing, but other than that... you MUST be focused. Nothing else is more important than this. Somehow, you have to get to that point before you can truly drive.
Second: If you can avoid manual cars, do so. With the sort of confusion that you say you have here, a manual transmission will simply make that much worse. With an auto, you dont even have to concern yourself with it. Hell, you couldnt pay me to drive a manual, I can tell you that, not even with as much time I've had driving. It'd be a disaster waiting to happen.
Third: Others above have mentioned practicing in parking lots and stuff. Definitely agree with this. For the love of all things puppy-shaped, do not try to get onto ACTUAL roads until you're fully confident in your ability to make the car do what you want without any confusion. The moment you get onto an actual road, you add other drivers and hazards into the mix... it's important to keep that in mind. No matter what anyone nearby may say, dont get on normal roads until you feel truly ready. Once you are on normal roads, try to stay on country/back roads as much as you can (if this is possible, of course... obviously this isnt really a thing in urban areas)
And the final thing: Be aware, driving can be scary sometimes. It *is* dangerous, and that's a fact that will never change. Never think that it isnt dangerous... dont underestimate that aspect. But believe me, if you can get past the hurdles of learning to do it... it's worth it. It's SO worth it. As long as you act safely, that is... dont try to jump over the Grand Canyon or something.
However: If you ever find yourself afraid of the car, afraid of the road... DO NOT DRIVE. Seriously. DONT drive while under the effect of fear/paranoia or even just too much anxiety. Just... trust me on this one. But when you're feeling up to it, feeling confident... yep, it's good.
Good luck to you!
