Most vehicles have several areas of glass which could comfortably accommodate a reasonably sized sticker without causing a problem.
Why is there glass there in the first place then?
1. Because it makes the shape of the glass more regular, allowing for easier manufacture and installation, and improved structural strength - remember that in more recent vehicle designs, a certain amount of the body rigidity is gained through the front screen (not sure if the rear screen contributes as well, though it wouldn't surprise me if it did), so there's more involved in selecting the shape and placement of the glass relative to the rest of the bodywork than simply whether it provides a view for the driver.
2. Because whilst it doesn't provide any visibility for the driver it does provide extra visibility for passengers.
3. Because different drivers have different seating positions and eyelines such that a piece of glass which may provide visibility for one driver provides no visibility for another.
4. Because the vehicle designer simply thought it looked better to use glass for that particular area of the bodywork.
5... ? I'm out of ideas now, but I think 4 different reasons for a piece of glass being there when it's of no apparent use to a particular driver should be more than enough to answer your question.
e.g. On the rear screen of my car there's a decent sized strip along the lower edge where, sitting in my usual driving position, the only thing I can see through it is the boot lid. Another driver sitting in the exact same car, but using a slightly different driving position, may very well be able to see something more useful through that particular strip of glass, but for me it would be the ideal place to place a sticker. Similarly, the quarterlight on the right rear door provides absolutely no visibility from the drivers seat thanks to the thickness of the door pillars and the shallow viewing angle, so plastering that with stickers would make no difference whatsoever to my visibility.
The reason I have genuinely questioned this is because there will no doubt be someone somewhere who may actually put the sticker in a dangerous place (someone with no common sense!!!). If this person does and it causes an accident, that is still one more accident that could be avoided.
Another reason is simply because of visibility. I thought that the whole point of glass in the car was due to this. If you think about it, as a driver you use all of the transparent parts of your car to aid visibility at some point. For instance, using a back passenger window helps you when checking over your shoulder. Wouldn't an extra sticker compromise this??
I also wondered about the construction of the window sticker in question. Why can't you just put any sort of sticker on your motocycle helmet??? Because certain chemicals can destory the protective surface of the helmet. I was just wondering whether or no certain adhesive chemicals can actually penetrate the glass and destroy the structure, without being noticeable by the human eye?? A genuine question I am sure you will agree, and an important one considering the fact that the car chassis structure is built around the glass as well as the metal.
I am not trolling, I just like to argue and debate things. Its funny how some people think that when a challenge comes along. At least you are providing decent answers, not like some other people on here!!!
