I attempted to video some driving in the rain to show the water carried behind the car but it didn't turn out as good as I was hoping. I need to mount the camera differently, and I also need it to rain harder...haha
So its not super easy to see, but there are a few good moments where you can see a bit of haze behind the car. It doesn't stand out from other cars very well, but I can assure you it is much more water.
The audio was a ton of loud water droplets so I added some classic "Orion" to be more pleasing to the ears
