This map was created for a video to answer one question: is it possible to fully charge an electric vehicle using only regenerative braking? This is a specialized, intentionally minimalist environment. It is simply a long descent to ensure that the races are repeatable, the comparisons are fair, and the recording is clean.

 During the experiment, this descent was used to accelerate electric vehicles from 0% to 100% charge solely through regenerative braking (without the use of chargers or refueling). After someone requested this map, I decided to publish it so that anyone could repeat the test, compare different electric vehicles/regeneration settings, or use it for other purposes.

Warning: This map is at an extreme altitude (~50,000 km). Regular internal combustion engine vehicles will not function properly due to a lack of oxygen (no air for combustion). Electric vehicles are recommended. Unless you want to push the vehicles manually.
