Never let it be said that there's nothing more any one can ever learn
I picked up Advanced & Performance Driving by Reg Local the other week, and have finally worked my way through it. Some will know Reg (not his real name) from PH, and basically this book is a collection of his thoughts and ideas of modern fast road driving put into print. He's ex-advanced police driver instructor, so as good as you can possibly get, but he's also an excellent writer who comes across with a good dose of common sense as well as humour.
There was masses of info in there that I'd never even considered, some really silly tips and tricks that not only make you safer, but also faster and smoother. Give you an example: When approaching corners, slow down more than you need to so you can accelerate through them. This makes for a smoother ride for your passengers but also allows the rear suspension to work properly in the corner, actually increasing your grip and speed. Having tried it a few times, it feels odd at first but after a while you just 'get' it and you are noticeably quicker. And then there's "OOoooofff the brakes...", which I'm working on at the moment.
What also surprised me was that some of the more advanced techniques he mentions I already do without thinking, which was rather pleasing and I'm sure many of you folks on here will read it and realise some of what you do is also the correct thing already.
It's a really cheap read on e-book, and not exactly expensive in print either. You could do much worse than give this a read, you really could.
