I found a similar design on the internet and the shop in the pic adjusted the design on computer first then worked layout for 2 days. As far as the posibilities of getting a ticket from police..yes its possible. But the police are mostly cool. Everyone in Florida tints windows. If one gets a ticket your just required to remove and use a less % tint.
In answer to your question has anyone been prosecuted. Its an offence to have a tint in front of the B post that restricts light by a certain percentage. The figure is not high about 13% I think. And yes there have been prosecutions, but in the UK its usually dealt with under the vehicle rectification system. That is you are given a time period to put it right. Although in the daytime there isn’t too much of an issue its in the dark where light levels are affected.
