I've never failed a LRA despite having no rear window decal once. They usually ask me to roll down all the windows and lay the safety equipment out in the boot. Then they take a photo or two, ask me to print a receipt and tell them the mileage and (for the last couple of years) tell me that the passenger side door sticker won't pass again. Whole process takes 4-5 minutes. I even discretely offered the inspector a drink (folded well within fist size) for overlooking the decal that year and he refused to take it.
I'm the same rats, except last year he wanted to see the footie lit up, but I has LEDs in it donuts difficult to see during the day.
I've always drive into the spot as my front bumper has a crack in it and it's always passed. Again last year the chap told me to reverse into the spot so when I done that and then stood in front of the crack
