London's Drive to Work Day

So, take the day off. Drive around and around west end, city, just having to pay £8 plus fuel (loads). Never stopping. What on earth should the massive signs on the car read?
AM I IN YOUR WAY? NORMALLY I CYCLE HERE
MY OTHER CAR IS A CYCLE
DRIVING YOU NUTS

Good point skully
we do need a flag or something to let people know that some drivers on the day are normally walkers/ cyclists/ bus riders.

we do have a poster now thanks to zazcar

Which may be tweaked a little
