Yeah, they're called frits. The perimeter of a car windshield (windscreen if you are in England) has a series of graduated dots that transition into solid black. The graphic pattern is enamel that is baked to the glass and used as a primer to hold the windshield to the adhesive that secures it to the frame of the car.
Primer is part of the function as the graduated pattern hides the glue line of the adhesive making a nice aesthetic finishing touch.

Last year I had a cracked windshield (probably from a stone on the highway) and the insurance company offered me an aftermarket windshield that was readily available, or an OEM (Original Equipment Manufacturer) from Toyota that would take a few days to get. Since the crack wasn't through the glass safety laminate and I had time, I opted for the OEM glass and the frits were the same.

hello.. handshake

this blog is goodthumbs up

On some cars of the older days the windscreen was not even glued.
Bmw e30 for instance (I took my drivers license in one of those back in 89.)
Those cracked almost never.
Since todays windows are glued to a frame, a frame that twist slightly
during driving but the window is rigid so the tension makes it crack after the initial
flying stone.

Toyota is all over good cars. Only the D4D (diesel) have head gasket problems
after a certain amount of miles almost always.
Chatillion why is diesel so expensive in the US, any idea?
Here it's cheaper on the pump. I tend to drive a diesel.
At one time, diesel was less than gasoline.
I'm not sure why it's so much more now.
Why does diesel cost more than gasoline in the US?

As both motor fuels are made from crude oil, some may expect the price of diesel and gasoline to be fairly closely linked. However there are a number of factors, from taxation to manufacturing costs, which actually make diesel more expensive to buy.

The major reason for the cost disparity is the high federal and state taxes levied on diesel, largely due to the carbon emissions produced. The federal tax on diesel is currently 24.4 cents per gallon, as opposed to 18.4 cents for a gallon of gasoline.

The rate of tax levied by states varies massively, but some add as much as 74.1 cents per gallon of diesel.

It is also important to remember that the demand for diesel is often very different to that of gasoline, meaning that they are affected by different factors. Diesel is typically used in industrial processes, machinery, generators and large delivery lorries. Therefore when the economy is growing the demand for diesel, and therefore the cost, increases. Gasoline is not subject to these pressures in the same way.

Aha, that seems to be the case yes. Here they tax diesel less harshly.
Personally I think your policy is more correct. Cos the nox is worse than co2
for the lungs in my view, even if much is filtered.
