Everybody sometimes forgets some trash inside the car, be it a parking validation ticket or maybe a receipt from the grocery store. But eventually, you see the piece of paper (or whatever else might be forgotten) in the door pocket and take it to the trash bin.
With this being said, it’s hard to understand how some people get the interior of their cars so dirty that it looks like the inside of a vacuum cleaner. Case in point, the video embedded above shows a red 2013 Dodge Dart that has seen much better days, at least on the inside.
