A guy doing this wrecked my car years ago. I was parked in front of a grocery store and when I came to get it in the morning my car was covered in what looked like about 50 gallons of vomit and every inch of it was scraped up. I got the grocery store to show me the footage on there it was a guy doing exactly this and multiple broke open and landed on my car and got rotten soup in my vents, under the hood and seals , was a nightmare.
