Depend on your definition of 'good' really I suppose.
See, due to buying a car early on in life and driving company vehicles of all kinds (From small vans to 26tonne loading shovels) from the age of 20, I learned how to abuse them. I can slide, handbrake, drift, J-turn and reverse flick if I need to. I once managed a 360 degree spin (trying for it) in my Nova in a quarry I worked at. It's not hard to learn if you've got the chance. This means I can, if the fit takes me, drive like a rally driver pretty much anywhere.
But I don't. I know I can, so I don't need to prove it, and I wouldn't do it with anyone else around.
It also comforts me to know that if something goes a bit Pete Tong, there's a chance I'll know what to do and I'll come out unscathed.
So if 'good' is being able to control a sliding vehicle like it's second nature, then yeah, I'm not too bad I reckon.
There's more to it than that. I used to drive flat out quite a lot. I've never had even a moderately quick car, so this wasn't really a problem. I'd do 80-90 on the motorway, that sort of thing.
But driving a lot for work made me give that up. You just can't do it and get away with it forever, either from a legal or safety point of view. You'll crash or get points, won't you.
So, I gave it up. I just cruise round gently, trying not to brake, trying to be smooth, trying to use the throttle as little as possible to save fuel. That's what it's all about now, isn't it?
65-70mph on the motorway is fine. I set the cruise, get some tunes on and relax. Everyone goes blabbering past at 90, and I don't get involved. I don't have to concentrate as hard as my speed is lower and I'm not constantly looking out for The Law. Being 'a good driver' is neither here nor there like this, really. I find I don;t get wound up by others as much. I just chill.
I'm also commuting 50 miles return by motorbike in heavy traffic every day, and you CANNOT do that at full tilt and live long. Nice'n'easy does it. There's no rush.
So, TBH, I don;t really know if I'm any 'good' as such, and nor do I compare myself to others. What I do know is this:
1) I'm smooth. That's how I was taught. I like to see a racer with a smooth style and I've had 2 instructors tell me I'm smooth. I like to drive/ride like that.
2) I'm better than I was. I'm more chilled and safer for it, and I've had some advanced training, some track time, and I've got the naughty stuff out of my system early on.
Don't get me wrong, give me an empty road and an Italian v-twin and I'll give it a proper thrashing, purely for my own enjoyment you understand....
