Because at the end of the series, when Azula tells them to fight in an Agnai Kai, they both say, simultaneously, "But Azula, we're not Benders".

You are basing this on nothing. We don't know what powers the tanks, but we know most of the scout balloons are powered by shovelling coal into a boilers. We only see a vehicle powered by bending ONCE in the series, when Zuko firebends into the boiler of the scout zepplein with Sokka. Given that we see the Zepplelins being flown by that inventor guy, I'm pretty confident they aren't solely powered by fire bending.
Actually, I semi-take that back; the Earth Kingdom APCs they use on the eclipse day battle are definitely powered by Earth Bending.

My point isn't that this tech couldn't have arisen, but that because Republic City is such a melting pot, that Bending based technologies or ways of life are being phased out.
I actually almost wonder if the theme of this show is going to be how Bending is bringing the world out of harmony.
