Incorrect latch usage
If you have not been concerned over the latch system enough, maybe it’s time for you to ponder about this. Most cars do not allow the latch to be used in the middle seat. It has to do with the anchors, thus a middle seat installation would be unsafe. Also, the seatbelt install is more difficult than the latch, but is as safe when done correctly. Using the seatbelt and the latch together is actually less safe than using one or the other. This is because the seat must still be able to move during an accident and using the seatbelt and the latch together would cause the car seat to be overly tight.
