Keep in mind transitional lenses react to UV to auto darken. The windshield of a car has a UV filter and blocks UV. Therefore the glasses will not work behind a windshield or windscreen where UV is being blocked.
Since Transitional lenses work on a biological process, extreme heat can diminish the transitional effect of all transitions type eyewear. In most cases freezing the glasses can re-activate the glasses.
