In the following sentences, what kind of implication/connotation do they have when they use "get to +verb" structure instead of simple verb structure just like "I drive the car", "I swim everyday"?

"I get to drive the car on weekends"
"I get to swim every day for free at the public pool"
"We get to go to the beach tomorrow because it's a holiday"

Here is a sentence using "got to" I encountered in a book.The context is that a mother received a call from her university daughter living apart.

The excerpt is as follows:
We went back and forth like this for a while. It was a welcome break. And I got to hear more about Maxwell the boyfriend ...

According your definition, I presume this sentence suggests that the mother wants to know more about her relationship with her boyfriend but since the matter is very personal, she asked her daughter in some way if it's ok to talk about it and she managed to get her permission. I wonder if I am right?

I'm surprised that your reply came while I was thinking and writing my reply to @dongelev85. Thank you so much.
I would appreciate you if you could take a look at my question I made at my reply to @dongelev85 and let me have your opinion.

Thank you so much for your assistance. I fully understand what you're saying. But It seems that I need to be born as a native to learn how to use "get to"

An easy phrase goes a long way but sometimes can be hard to learn for a non-native, especially such as this one whose meaning develops in accordance with context it is used.

Thank you again and I'm sorry to be late for reply.
