These kind of crashes are similar to those in the second video ever in BeamNG' YouTube channel (and colors and cars were the same too (minus the dirt haha)
Noticed this instantly too, almost like he is using cubemaps and than has very high alpha and darker brightness settings for the cars on the colour menu. Ironically his user tag is "CryDev" And that 2nd vid was from back on Cryengine. Fun to note he isn't using Cubemaps based on bumper/light textures.
Well this video belongs to an video which was released at 7/7/2012. So it´s a BeamNG 2012 vs. BeamNG 2015 thing.
