Re: Lets talk about window tint
Not sure where everyone lives, but note that some states -- California especially -- allow only a slight darkening of front seat and windshield windows. I don't know the exact darkening numbers (stated in the State Vehicle Code) but if the driver can't fully be seen in daylight that is definitely too dark. Apparently the law is for safety, for other motorists and for police officers.
Of course cars factory-built for California have legal windows. But when someone with a vehicle bought elsewhere moves to or works in California, even for a few months (which triggers "vehicle resident requirements"), if windows are darker than California allows, cops can and will write a ticket that requires replacing the glass. Expensive! This is a common situation with cars from next-door Arizona and Nevada.
If too-dark-windows are implemented by adding film, apparently it doesn't matter how long the car is in California. A cop will stand there while it is peeled off. This is a common site along the border with cars driven in from Mexico.
