How good of a driver are you?

Recently I have had to take an online drivers course because I was inattentive of my speed driving through a neighborhood. Boy was I angry about that ticket. Anyhow, I am able to get it scrubbed from my record for completing a drivers course on line.
Needless to say in 25 years of driving, I thought myself an excellent driver for always being cautious. After reading through the material on line, I have discovered new laws and things I did not know.
There is a whole section on what to do for different car emergencies that I had never considered.
And how to handle or observe for signs of an aggressive driver.
Having moved up north for instance, I never knew it was wise to keep your tank half full.
Or how to visually tell if your tire is over inflated or underinflated.
There is a lot more that is covered that I was unaware of simply because I have not had the occassion to experience it. Doesn’t mean that I never will.
This course has certainly open my eyes about a lot of things, that as a driver I feel I should’ve known all along. It certainly has helped increase my confidence and knowledge and is a blessing.
Upon review, I would have to say I was average and lucky.
So do you feel you need refresher course?
How long have you been driving?
