Plus in Europe it's forbidden to tow with a rope like he does. You must use a rigid link, like a bar or a tube.
Not true, a rope is fine.
The most spectacular example of regenerative braking are trains that are used in Scandinavia, heavily loaded with iron ore that is transported to the coast: "In Scandinavia the Kiruna to Narvik electrified railway carries iron ore on the steeply-graded route from the mines in Kiruna, in the north of Sweden, down to the port of Narvik in Norway to this day. The rail cars are full of thousands of tons of iron ore on th…

What if they had a Tesla merry-go-round where instead of charging your Tesla, you connected it to this giant horizontal ferris wheel that spun it around and charged the battery? It could be wind powered!
I guess conveyor belts under the wheels would have similar results, probably with less moving parts. But then... why bother, just plug the car to the power source making your marry-go-round go round! Otherwise this is a lot like putting salt on a birds tail to catch it... https://en.wikipedia.org/wiki/Salting_a_bird%27s_tail
Regenerative braking is so neat. I drove up a steep windy road to go on a hike with my plugin hybrid. On the way down I tried to let gravity do all of the acceleration and regenerative braking do all of the deceleration. At the bottom of the hill I had racked up +3 miles in total. Another fringe benefit is that brake pads wear out slower and produce less pollution.

I think the wind at his back is key here. His car was acting like a wind turbine
I think OP meant winding and not windy, but even if not, Teslas (and any other car) are designed to be aerodynamic, not the opposite, so it's quite impossible to yield more energy than it cost in that scenario, even ignoring motor efficiency, regenerative braking efficiency, and every other real world inefficiency.

It’s likely fine, 65 kW is only ~85 HP. Simply maintaining highway speeds is ~25HP, so as far as the tire is concerned it’s the equivalent of mild acceleration or breaking. The regenerative breaking system is likely designed for long mountain roads, so it might overheat but probably not.
Teslas will switch to friction brakes when regeneration limits (peak current or battery SOC) are exceeded. I’ve sustained constant 50kw regen while downhill through Appalachia passes, no issues, with the caveat that regen current is limited if the pack is cold until it approaches operating temperature (yellow dashed lines on the regen current display indicate your reduced regen capability).
A great omission.

Teslas have no resistor banks? A great omission.
