I, too, thought of that as we looked through all those photos. Even if the cart had a front axle with a steering mechanism, then when negotiating a curve, the rear wheels would attempt to cut into the radius of the front wheel curve. On the other hand, if all the wheels were caught in deep grooves, the cart motion would lock-up part way through the turn. It might be possible for a wheeled cart to make such uniform tracks on a curve if both axles had steering mechanisms with the rear axle perfectly compensating for the turn radius of the front axle. But I just don't think that's a plausible explanation of those tracks.

Totally agree.

No matter how you slice it, the tracks simply do not conform to the logic of a wheeled cart. And that doesn't even consider how the "vehicle" was powered, especially if it was heavy enough to cause that kind of uniform deep rutting. Besides, what are the chances the any cart would follow exactly the same path each time? It's virtually impossible that those tracks were made into solid rock by passing over the exact same path and knocking off a few molecules of stone with each passing. In the very least, if these troughs were caused by a wheeled vehicle, then you'd see a wide, shallow trough that eventually narrows as it deepens toward the enter of the trough with further wear, but that's not what we see.
