<human>: Can you provide a brief rundown of the text in within 3 sentences?

A few days ago I was getting into my car and noticed that there was stuff on the seat so i decided to put it in the house real quick. I had my Nexus 7 in my hand so I decided to set it on top of the car and put  the stuff in the house. I was in a rush so i hurried back into my car and drove away, TOTALLY forgetting about my tablet.. I was driving around for about 10 minutes and nothing happened (i still didn't remember about my Nexus.) This is where i took a right turn onto a fast road, 40-45mph. I accelerate, the tablet slides down the car, hits the trunk, and BAM hits the road. I was like OH SHIT!!! So i find a place to turn around as quick as possible and on my way back i see cars going 45mph approaching the tablet on the road.. This is when i went berserk. Five cars drove over the tablet, two of them ran over it. And i saw EVERYTHING. Any chance of my tablet being spared was gone. I stopped on the road (no cars were coming) and ran out to retrieve my tablet. It was absolutely destroyed.
<bot>: I Left my Nexus 7 on top of my car. It fell off and got ran over by multiple cars. Shit.
