I know all about Doppler shift but still don't get it.
The cartoon is a play on the usual audible Doppler shift but with light.
Light is blue-shifted if the source is approaching you, red-shifted if receding. Blue car approaching, red car driving away.
There might be an underlying comment about speeding but only the artist would know if that is true.
Ok thanks.

"A couple with some dogs just came up to the window and were having a look in, but they walked off really quickly and I didn't think anything of it."
"I didn't know until after we left that these people phoned in saying that there was a mass murderer; they were wearing a robe and they were walking over all of the people, and it looked like some kind of ritual, and that the people on the floor were actually dead.".
