That in fact is one of my key criterea for a dream car these days..... I found that driving a track ready car on the road had several issues:
1. Police seem to pull you over more often when you have a 6 point harness, racing seat, and are sitting with your eyeline just over the dash (so you don't keep whacking your helmet againt the full roll cage...)
2. getting in and out at your destination gracefully from said seating position in point 1 not so easy in anything other than a racing suit.
3. Trying to parallel park while in said seating position described in point 1, as well as big rear wing near impossible without a pit crew member guiding you....
4. Clutch heavy in traffic jams..... Luckily I had a normal one. Carbon multi plates are a dog in traffic - you'll burn them if you ride them, so it is basically redline and drop it - and hope the car in front has moved sufficiently...
5. Fuel - having to plan your trips based on where the correct fuel will be available before you run dry is irritating. (ok, ok, exaggerating - program your ecu to run lean....)
6. Interesting side effect of low suspension setup and splitters - can not get into every petrol station mentioned in point 5 due to angle on driveway. Also may not necessarily complete all speed hum crossings without losing various bits of aerodynamic aid and componentry.
7. Interesting side effect of stiff suspension/chassis set up - bent wheels when going over rail way crossings. Also broke engine mounts regularly.
8. If you are running hi temp brakes, they need to get hot before they work. Forget corbon discs or pads on the road - just does not work at legal speed limits. I found ceramic pads on steel rotors are a good compromise
9. Radio/CD/any entertainment?? Come to think of it, where's the aircon!
10. Passengers seem to have a hard time sitting on the floorpan with the fire extinguisher (no seat...)
11. Catalytic converter - oh, you need one of those? Damn!
12. People think it is fun to play with the switches on the outside of the car with the red or blue triangle pointing to them
