I agree, my driving is more agressive now and I use chances I get much better now. Much more comfortable in the car as well, I know how it will react and that makes me more confident.
But there is naturally room for improvement, I still do stupid, stupid mistakes.
I recognize the cars pretty easily in the rear view mirror, all the cars have pretty unique looks when you know what to look for, I also know what their starting position is so it's really not difficult to see.
