This Russian-language (?) video shows a handy car accessory. Drive up on the treads, remove your wheels, attach the axle to the treads, and you have a functional tracked vehicle.
I like the Build It Yourself approach to that thing- This guy had a problem. And instead of buying the overly expensive Mattracks that won't even work all that well in the wet landscape where that guy lives, he builds something himself. And with some extra tinkering, that problem of extra wear of those u-joints can be solved soon enough.
Step 1: Purchase a lightweight rear-wheel drive vehicle (AKA sports car in many countries) Step 2: Drive said vehicle onto tank track contraption. Step 3: Unbolt driveshaft and reattach to live axle on track configuration. Step 4: Drive vehicle in new configuration. Step 5: Try driving vehicle quickly in new configuration. Step 6: Replace driveshaft u-joints sooner than normal because of excessive wear caused by increased driveshaft angle.
Lori Dajose, CalTech Communications Officer: "The original 'rabbit illusion' was a tactile illusion," Dajose says. "You tap someone’s arm very quickly in two locations (let’s say point A and point B) repeatedly. When their eyes are closed, even though the tapping is only happening in two locations, they can feel the tapping 'hop' linearly across multiple locations on their arm between point A and point B. So for the audiovisual illusion, the 'rabbit' has to do with how the flash 'hops' across the screen."
