In the military I learned the importance of "getting the 'gouge' before any test. "Gouge" means passdown information from others who have been there. Then you practice, practice, practice, then take your own practice test until you can't possibly fail on the real one. Have you taken a driver's training course? They're worthwhile with the right instructor.
After you've passed your driver test, you'll live longer if you assume everyone else on the road is texting while drunk or stoned. Never go through a green light (for example) without making sure someone isn't running the red.

Driving is something like soldering that you get from practice. At first you have to look like an ass, at least I did. I don't know what motivates people who want to teach it, but don't let them get you down. It comes with time.

I think they should work out a way to price roads by supply and demand rather than a flat toll. So there would never be traffic jams due to volume.

They'll be putting assist into cars to prevent violating traffic laws and eventually the cars will be fully automated. That has its ups and downs but I think it's coming.

I also think the whole notion of people carrying thousands of pounds of metal around with them is a bad idea. We end up making big parking lots and large areas of grass to separate buildings from noisy highways. Then it becomes difficult to walk or bike anywhere. When we drive two miles to the store rather than walk it has health consequences from not exercising but also from the stress of life-and-death decisions without corresponding physical exertion, something I think we're not adapted for. The decreased density means it's more difficult to get to nearby neighbors. You're less likely to see them walking down the street.

On top of all this, moving all that metal takes a huge amount of energy. Energy runs the economy. Energy from burning fossil fuels threatens to incur huge costs on future generations in the form of global warming. We aren't even sure of the magnitude of the problem. It could be smaller than we think but it could be near catastrophic. We're taking a huge risk by not taking it more seriously, by not factoring in the costs we're pushing off on other people.

That being said, I use my car all the time since I bought it five years ago. It was going to a supplement for when the bike and bus are inconvenient. I still use bike and bus, but they're the exception. 85% of my local travel is now by car.

I remember feeling so awkward learning to drive 25 years ago. I think it's good you take it seriously and are nervous about making a deadly mistake. That's better than many drivers who seem oblivious to the perils.
