I'm glad y'all appreciated the humour.
And no, those images are not Photoshopped. I saw the first ENX one while out for a bike ride on Sunday. I just spotted it out of the corner of my eye. Lucky thing I had my camera with me.
After that I started watching the plates more closely, and found the EDX a few blocks later.
I thought some of you might have gotten a chuckle out of it.
