You are of course forgetting that many of us 'autobox boys' have been driving manuals (often very fast) since way before you were even a smile on your Dad's face
. Don't worry, you'll probably learn to drive fast/quick/safe as you get older, even with an auto (which if driven properly do have control and speed (though not usually to the finite offered by traditional manuals)) 
Perhaps, but lack of practice driving proper cars, coupled with the slower reactions of an oldie can't be helping matters 
I can drive fast/safe/quick perfectly well at the moment, although admittedly only with a real car that is actually under my control. Doubt I'll ever learn to do it with an auto though, as the things bore me to tears to the point where I just can't be bothered pushing on any more, and usually drive it like the old man it was designed to be driven by 
Erm we have all had "Proper" cars, I have owned a car, not particularly fast but would out handle ANY you have owned, not out corner probably but position accurately and be fun.
And 90mph on loose chippings when you won't do the same road at 80 in the wet and when at 100 a Mondeo I was following was lifting a wheel was fun.
Yes I was looking out of the door windows!
Never take on small Rootes hatches if they are either stripe down side, spoiler fitted, or have large exhaust.
If you want to learn how a car handles buy your self one of the following
1) Mark 1 or 2 Escort 1600 or 2000
2) Hillman/Chrysler/Talbot Avenger
3) Vauxhall Chevette HS
4) Chrysler/Talbot Sunbeam
All are commonly fitted with better suspension and engine mods, and will teach you more about car control than most modern cars.
Note all light, small, RWD, fastish (modified if necessary), and have done well at rallying.
