I rented a Toyota Venza, a small SUV. Here is a picture of the trunk:
The material of the bottom of the trunk is some kind of plastic, slippery as Teflon. I put my suitcase in there and it slipped around constantly, making a terrible ruckus. I was not even able to change lanes on the freeway without the suitcase slamming right and left. The slightest acceleration made it crash against the door. Gently stopping at a traffic light, it slammed into the back of the seats. This got so annoying that I had to pull over and take the suitcase and put it in the backseat.
What were the Toyota engineers thinking when they designed the trunk material like this?
