The only photochromic lens, I know of, that darkens inside a car is Transitions XTRActive. They darken moderately inside a car, probably to about 60% or 50% light transmission and supposedly get very dark outdoors.

I don't have a UV light, unfortunately. Can you recommend any place that might let me use one for five minutes?
wonder if humidity also play a part in how dark the lenses get ?
Looking at your pics, it looks like to me there following are possible scenarios:
1. The lens has manufacturing defect
2. You've been standing in the shade on a cloudy day when you took those photos, or
3. The lens is approaching end of life and does not do transitions as well as it's supposed to
Bear in mind photochromic lenses have a life span of 3-5 years only, and wears out the more they perform transitions. Therefore a brand new lens may have been ex-demo in the shop for a few years and thus lead to the 3rd scenario mentioned above.
If you need testing of your lenses, take them to any good optical store as they'll have UV testing machines to demo their photochromic eyewear. Transitions would kick in within 30 seconds and by 2 minutes should reach almost its full potential. If it takes any longer then it's approaching end of life or you've got a dud
