It's all relative... if you have shit tyres you need to be more careful. If you have good tyres you can push them harder therefore not needing as much precaution. There's still a choice, it just means I drive more subdued that someone with good tyres if I want to keep traction.
Rekin: Again, all relative. I drive the Ring road home and to work every day, I see plenty of accidents and I have never come close to sliding into a car, even in the wet. It would be the same with good tyres. As long as you know they are shit you can then drive according to their quality. With bad quality tyres my following distance is extended. I've emergency stopped enough on a bike in the wet to know the ultimate "Holy F**k!" situation which included losing the front end (somehow I didn't drop it), it certainly makes you aware of braking distances in all vehicles.
I know what you must be thinking and I would probably think the same about someone that said what I said if I didn't know them. If you can take all of the above into consideration I hope you understand that I don't play with fire without knowing how to control it. Will keep you posted though. If I do end up someones arse I will definitely let you know and appologise as I can definitely accept that my experience and knowledge has a long way to go.
