"slow" is a statement of SPEED and speaking of zero-to-sixty is ACCELERATION, so it would be more accurate to say "0-60 in 7 is a very long time these days" but I digress.
I quite frankly don't see any huge difference in going from 0-60 in 7 or 5 seconds. The frequency with which you must do this is tiny.
However I totally agree that it's useful to be able to (as mentioned above) stop very quickly, or accelerate from say 40 to 60 very very quickly.

. Also I don't know where you live but I don't think I've EVER been on any highway anywhere in the continental US where people are going 60 in the leftmost lane. Hell I typically go 75-80 on EVERY highway whenever I drive and I've never once gotten a ticket for speeding...
