Is it just me, or am I seeing the motorist's atempt at saving the planet?

[Dave Taylor]

For weeks now on my travels around the North, I have noticed more and more cars and vans with only one brake light, and in some cases one brake light and the high level light out as well (10 today in a trip to Conwy and back to Bolton).
Is this an atempt at saving the planet?
Or is this some new Tin Top secret CULT, and this is how they identify each other?

It's not hard to see if you look in the rear veiw mirror when at the lights you can see the reflection of all three lamps.

But best for me was the Police Traffic Car at the lights the other week. I attracted his attention, When he wound the window down, I said excuse me Officer you have a brake light out, "Oh, right Thanks, I didn't know" my answer "Neither did I when I got a ticket".
The good thing here is the Police car is unservicable and must return to the garage to have the bulb replaced.

Oops, it just came to me if he's off the road Who's going to tell the law breakers they just got busted...
