I see lot of people struggling with specific mechanics (wheel axes, diffs, etc). I don't understand well them all myself. We can see on google, technicaly what the element does, but not what it changes on behave of the car with pros and cons. why not make ingame explanation axed not technic but behave with pros and cons. 1 scenario for each of these mechanics so people can try it and see how it affects his driving. Scenario doesn't have to be long, it could be just a climb u can't do 2WD for example and you have to go 4WD.
That's a good idea, using BeamNG to teach people about how different parts physically affect the vehicle
