I am what is called a "timid" driver, so I guess that means I drive too defensively. I'm not a great driver.
But........
I can parallel park with the precision of a great surgeon. I have no idea why. It was one of the first things I learned to do, and I can parallel park any vehicle, anywhere, into any space, even if there is only a few inches leeway.........and it always amazes my friends.
I learned to drive on a stick shift, and am still driving ......... a stick shift standard transmission vehicle. I think having an auto tranny would confuse me at this point
What I CAN'T do anymore, due to being out of the habit, is drive on big expressways with a lot of merging and high speeds. I used to commute to work on I-95 in Northeast traffic....my exit required that I cross over 3 lanes to GET off at my exit, and I did it on I-95 corridor loaded down with semi trucks and people who wouldn't let you in front of them if their life depended on it!

It didn't bother me one bit, even over ice and snow where you couldn't see the white lines.
Now.....Last week I had to drive I-540 up in NW Arkansas, I was going 70mph and people were whizzing by me like I was standing still, and it was very crowded.
I was getting white knuckled for a while there, and ended up getting off and taking some back roads. Just couldn't handle it.
