Not sure what the point is in tinting the whole windshield in the first place

I have a tint strip and I'm going to make it 8" instead of the 4" it is now. Just be careful. I got a $200 ticket in my b/f's car (who is a LEO, btw) for having 20% tint on the side windows. My camaro has 20% tint as well. It's a chance we take but I venture to say, they will make you remove that on the spot if you get caught. They can also tow your car if you get pulled over for any tint cuz it is a safety hazard, its a stretch but just something to keep in mind.
