Where do you placed your car stickers?

If you have a car, you definitely will have at least ONE car sticker, which is the road tax. Most of us will have 2 -3 car stickers, one of it, the road tax, then maybe another sticker is for your car to enter your housing area, then probably will have the insurance car sticker, the parking lots car sticker, club membership car sticker, the 'P' sticker and etc.

Where do we normally placed these car stickers? Well, normally people will placed it on the left bottom of the front screen, one by one from down to up. I've seen ppl placed it at the middle of the front screen, although it looks a bit weird to me, but as long as it doesn't blocked the driver's sight, then it should be ok.

BUT today, i saw someone placed the car sticker on her right side of the front screen. Not right bottom but right middle!! although the sticker is transparent, but still it's blocking her sight!! I wonder why she did that!! road tax on the left middle, then that car sticker (should be her housing area one) just directly in front of her!! What is she thinking? trying to see how good is her eye sight?? I wonder will police stopped her for that.. hmm..
