Wheels and the Cryonic Woman

[on:]

Just curoius, you know how in the "Mother's Day" episode where the robots take over the world, but then the Futurama crew needs to get to the cabin in the woods, they have fry build a carriage and he uses a wheel?  Well, the cast has never even seen a wheel, and they are curious has to what it was.  BUT in cryonic woman, when Fry and the kid race to see who will be leader of the pack, they grab on to some cars that are speeding down the highway.  They are not hover cars, these cars have wheels.  Like cars in the year 2000.  I just thought that was a little strange, and was curious as to if anyone had any kind of explanations what so ever.

Actually they used wheels quite often during the show. Even in Mothers Day you can see robots with wheels.
The explanation is quite simple:

The writers forgot about it.

Some writer: "Everything in the future hovers."
David X Cohen: "We had this idea that the technology of the wheel was lost somehow, and that's why they use hovercars. But sure enough, after this episode was made someone came up with a long list of things from earlier episodes with wheels."
The same writer: "Really? From the studio or on the Internet?" (Implied that if it was on the Internet it was just nerdtalk    )
David X Cohen: "Both, actually."

Here is the thread where I've taken it from: Wheels?

My take on it is that the wheel is a seldom-used, primitive gadget, and as such most people wouldn't think about it. I'm trying to think of a parallel in our time, but the only thing that comes to mind is the escapement mechanism in mechanical clocks.
