Didn't know about this thread when I got my tint ticket a month ago in SF.
I was running 20% all around and had it for three months.... until... I was stopped on a pretty busy street and got paranoid and rolled down my front windows because I saw a cop in another lane behind me. With my windows rolled down and the light turning green, I just slowly accelerated and the cop pulled me over. The good thin is that the cop did not check the front of my car because I have no front plate haha.
20 days later, I went to the shop where I got my tints done to remove it.. I went in not knowing that it costs $45 was pretty damn stupid of me..
Got the ticket signed and paid the $25. Will be putting my tints back on in a week or two though! Now I'm debating if I should keep my 20% or do 35% or 50%... hmm....
