At the 6:05 mark, Max's bedroom reveals a telescope, a skateboard, a free weight, and clothing (mostly shirts) left on the floor. While known to use his skateboard, he's never seen using the telescope. His free weights (which he admitted he never used) he left back at his former home and shouldn't be there, and there shouldn't be any clothing on the floor either since his constantly worn Steel Suit gives him whatever outfit look he wants or needs (making clothing, for him, uniquely superfluous).
As Max drives through a landscape that's at least reminiscent of Monument Canyon, Colorado, Steel points out a billboard advertising the world's largest ball of twine. By proximity, that would be the one in Kansas (east of Colorado) rather than the more distant ones in Wisconsin and Minnesota. Though past Copper Canyon battles have been fought in a nearby Monument Canyon setting, Copper Canyon abuts a salty, deep oceanic beach, where other battles have been fought. That would mean the Pacific Ocean, placing Copper Canyon along the western edge of either California, Oregon or Washington (all to the west). As another billboard proclaims the world's tallest thermometer nearby, that would place them in California. A final billboard proclaiming the world's longest hot dog, which would, in the U.S., put them either in Oregon, Ohio or Illinois.
Max clobbers Dredd with the world's largest ball of twine, which he would have to go inordinately out of his way to fetch just for that purpose.
Not long into a fight against Dredd and Naught, dodging energy blasts, Max says he and Steel can't keep this up all day - but with self-replenishing TURBO energy on their side, he supposedly should be able to.
It's summer in the desert. Everyone exerts full physical energy into their fight, yet no one succumbs to heat stroke. (You'd be hard-pressed to find anyone breathing hard, too.)
Dredd and Naught can't find Max/Steel when they enter Stealth Mode and become invisible. They should since Max, still running, would continue forming footprints and kicking up sand across the desert floor. Max should have stool his ground.
