I used to do it in my former Skoda Fabia and the window just collapsed. Thank Indian roads. I noticed there is a subtle final movement from "cracked" to closed and I guess there is a big difference in vibrations related wear. Toyota ran ads encouraging owners to crack windows in the rain and I noticed no final movement. But I'm not risking it.
