Palindromes are by no means human inventions. The genetic code is littered with palindromic sequences of nucleotides, some of them known to have critical functional significance.

Proposed application of this font: AMBULANCE, POLICE signs, highway info, advertisements, seen from the rear-view mirror.

Thank you guys, and dont't listen to the following.

To be honest, I expected a bit more interest. Palindromes are very exciting after all.
@Neoqueto: An example picture with a rear-view mirror? It would show the text reversed back to normal by the mirror, so what's the point?

@noneo: Yes, mirror is a better description, but palindrome is a fancy way of saying the same thing (well, not exactly). In this case the inspiration came from (English) palindromes, and it was a beautiful word itself.
