To each their own, but Seriosa, our cars WILL tow alot of different thinigs. If you don't want to fine, but the cars can do it. I'm one of 'those': I tow a jetski when I want, and usually have a bike carrier on the back during the summer (road bike).

When I autocross, I take the carrier off and rock. Last event I had FTD, and guess what: the hitch was still on the car.

As others have said, get a good hitch assembly and carrier, and you'll never look back. Go cheap, and suffer. BTW, I use a Chase Race hitch, and a Saris carrier. Saris is the best solution because it keeps a bike up off the road, so nothing hits, which is an issue w/other types of carriers.
