@GrumpyGregry, I see from an earlier post you like to spend your hard-earned on bikes. Now this is fine and dandy, and I can see how you'd want different types of bike to suit different tasks. The fact remains, though, that you've still only got one backside. Whichever one of your stable you choose, the others are going to be gathering dust in the shed, a waste of the earth's finite resources and that.
With bikes, it's easy to have a stable of specialist machines at your disposal. With cars, not so much. They're generally more expensive, and definitely bigger. So more often than not, you have to pick a car that ticks more than one box. I know that if I didn't have to occasionally carry the girls about, I'd have something other than a Clio Grandtour (they call them Sports Tourers in the UK. It's not sporty). How about some sort of track key. Performance is electronically limited to a reasonable level everywhere except at the track?
To braking. The reason ABS works is because braking performance is best when the wheel is still rotating. If you've locked a wheel, you've overcome the grip between tyre and road - it's not that the brakes are too good, more like the tyres aren't good enough. So the grip of the tyre plays a major role in braking. So all other things being equal, what's going to stop quicker: a Porsche with foot-wide Pirellis at £500 a corner, or the £60 Chinese ditchfinders on the average Corsa?
