They do seem to like pushing the boundaries.

What would happen if Tonka & Hot Wheels teamed up? I guess we would have this.

These are fixed-wheel machines, somewhat like those little front-end loaders you can easily see at construction sites. These bouncers do not turn by angling guide wheels, but by have motors for each wheel. Cut the power to the left wheels in travel, the vehicle will turn left, etc. That's how they can get those huge moon-buggy tires on them.
The drone camera works at times gives the illusion we are watching R/Cs in action.

A friggin skid-steer off-road amphibious vehicle? Shit yes let's get rich and start importing these bitches now

Wow. Pretty damn cool. Why have we not come up with these before? Plus, the whole idea that the motors on each wheel makes it turn almost like a tank is pretty cool. Could you image armoring one and slapping a turret on it? LOL
