Freeway sign

[Joe]

I think the sign is real.

I think the message is bogus.

1) The text doesn't look like little lamps, it looks like solid lines which someone then tried to blur, poorly.

2) Look at the reflections in the big rig to the right of the sign. There are two, one for the middle line of text, one for the lower. Note how the lower reflection on the truck is brighter than the upper, but on the sign, the lower line of text has (or would have) fewer illuminated lamps than the upper, and they are also farther away from the truck?

3) The implausibility factor.

I think we've been photoshopped yet again...
