Found out some more tricks in scenarios and so here is some courses to show off the capabilities of gravity in scenarios. Consists of 7 scenarios that have around 2 configs on each location. Each location has a different car.
The ones in Utah contains a custom city with buildings made out of bridges (because why not?) which may or may not explode. This has a gravity of equivalent of Jupiter. Also, the time is distorted due to the planet rotating so fast.
The 2 Hirochi Raceway scenarios contain some stunting and lots of weaving between barricades. It seems rather simple (at least, config 1) but is much harder as the gravity is set to that of mars. The scenarios contain a custom sky colour to reflect a red planet such as Mars.
Those in gridmap have no base gravity setting (as in, it does not have the gravity of a known planet) and is half that of Earth's. It uses the sunburst and has a very brightly coloured fog, sky and shadowing as well as sun scale colour.
Currently, two configs are in east coast USA and that consists of a rally covet (which, for some reason, likes to combust frequently). This features more sky colouring and even less gravity than that of mars.
As of V1.4.1, another 2 configs of scenarios around Hirochi Raceway is Gravity: Le Grande Prix. This is where the gravity changes in order of that of the planets in the solar system. The changes happen on every waypoint triggered
