Driving sucks and I hate it and I'm so glad my wife lets me be her passenger princess. That being said, in Texas, you kinda need to know how to drive just by nature, so I'm used to it, but I wouldn't say it has anything to do with maturity. There are highly immature people driving, that's part of the problem. There's also very mature people who should not be driving. It's a physical skill that has to be taught and developed, and a lot of people take that skill for granted because it's easy for them to grasp. Even little things can make it more difficult, I'm naturally right handed, but I'm left footed (I found out taking Tae Kwan Do in middle school after getting bullied) so learning how to drive with my right foot felt confusing at first. There's lots of reasons driving can be difficult for someone, it's a highly overstimulating, fight or flight sensory nightmare sometimes, and acknowledging that you don't want to put yourself or others at risk because you're not ready to master that difficult skill yet, I would say, is the most mature decision you can make.
