tinted to untinted windows

Have transitional tinted windows for the driver and passenger doors. Windows tint during thecday and untint has it gets darker. Untinted for safety at night and a tint for sunny days.

In theory, this is a good idea. I don't see it ever happening though, because some states/cities (ie. New Jersey, Los Angeles) don't allow tint on front vehicle windows as it is illegal. If Ford did something like that, it would be more cost efficient if all vehicles had this feature. Right now, that isn't possible.

I also draw attention to eye glasses as an example. Transitions are eye glasses where the eye glass tints or untints in different light...in theory, an excellent idea. In practice, not so much. They are not very effective. I do like the idea, though.
