Finding the saw-tooth tracks entertaining, I thought I'd try and replicate them with my hotwheels sojourner model using a grey baking tray, and some salt

By pushing the model from behind, but slightly off-centre, I simulated the effect of having only two driven wheels on the left, and three on the right



Almost uncanny Notice that the saw tooth is there on both sides, but is more verbose on the side with 3 driven wheels - which would explain the heavy saw tooth on the left, but less on the right in the navcam image.

I may try it with my lego rover and more salt on the patio tomorrow

Cool video :-) Take a look at this view of spirit's tracks

Its on a collision course with that large rock. It appears to stop, turn to aim between it and a nearby rock, then drives forward until the right front wheel dragging behind causes it to veer toward it again, then it stops and repeats the process.
