Alright, you guys can say "you're wrong, you're wrong, you're wrong" all day until your fingers bleed all over your keyboard, but until you actually back up your claims instead of just telling me I'm wrong, mainly you, "rondoman," I'm not interested in what you have to say.
Here are some examples of tint, and yes, you can tell from both the inside and outside how dark tint is.
Pic 1 - 2006 Pontiac G6 with 14% window tint. Tint percentage is proven by both the manufacturer and the cop who wrote the ticket for 14% tint.
Pic 2 - 2010 Lancer with 14% rear window tint and 25% window tint as proven by the manufacturer.
Pic 3 - the middle segment of this picture is supposed to be 38% tint, which is considerably darker than the OP's tint.
I'm done arguing with some of you shmucks on this issue.
Until some of you have actually installed window tint yourselves and you have dealt with the different percentages, don't tell me I'm wrong if you can't prove it.
