Query: So Very Unsafe!!!

I understand the reason for a product like this--it would be very nice for a child to be able to eat and play while in the car. BUT IT IS SO INCREDIBLY UNSAFE! If you were to slam on the breaks, everything on this tray would become a projectile, a projectile aimed at the child. I would also guess that the try itself would fly back and hit the child. Have you ever seen a video of a crash-test dummy? Everything in the car is tossed around with such force.Not to mention that you should never attach anything to a car seat that hasn't been crash-tested with that seat. Besides being unsafe it will void the warranty and erase any possible responsibility of the car seat manufacturer.
