The reason why I got the hitch was because sometimes I haul more than 1 bike.. Lots of times I got friends and family coming along on my day-tour rides, and it's always great to have company on these trips.

On the occasions when I'm only hauling my own bike, I use the hitch for convenience-- It's quicker and easier to just throw the bike on the rack rather than manhandle it into the hatch. It's also nice that I can open the hatch while the bike is on the rack, and the rack holds the bike a foot away from the back of my car so I don't ding my car with scratches from the bike.

That hitch is the best piece of aftermarket accessory I've ever bought for my car.
