Miscellaneous observations from an educational communicator’s perspective

Would this sign save your life? Shown above is an “instructional” sign I saw on a bus. It’s supposed to show you how to open the window in an emergency, but it is completely confusing. The two diagrams look the same, yet one has a red “x” over it. Why is one right and the other wrong? Let’s not wait for a life or death situation to be sure what we say is what we mean.
