Depends entirely upon what you want.
I have done any number of long trips in things like our old Vanagon, Benz diesels, our Aerostar, and various Hondas, and never gotten a ticket. The VW and the W123 diesels were too slow to attract police attention, and the Aero and the Hondas are too anonymous.
A 'Vette, a Porsche, or (lord help you) an F1 are the last machines you would want to drive, unless you enjoy being cop bait wherever you drive.
Let me hijack your thread, and propose a different fantasy:
I wake up one morning, shower, shave, dress, and walk out to the driveway. Some kind soul has sportingly left a Ferrari 330 P3, a Porsche 917K, a Lola T70, or a Ferrari 512S in the drive for my commute. This is nice, since I know where the po-po hang out, and I also know the rural roads on which to lose them.
I fire up whatever beast the kind soul has left for me, killing it three or four times in the driveway, while learning the clutch. I then drive the half mile through the subdivision to a four lane divided highway, and drive slowly to a small city, giving everything a chance to warm up. I navigate the two miles through the small city, with plenty of traffic lights allowing both additional warm up, and my gaining familiarity with shifter and clutch.
We then launch into 18 miles of rural two-lane bliss. We go down to second for every clot of traffic we come upon, and we blow by in a great rush of sound. I know where the cops hang, and I know that I can easily evade them.
Bliss!
