Surely this was Batman 1966's alternate car-build? (it's the 1962 Ford Seattle-ite XXI)

I think front dual was a bit of a thing back then but mostly on something like buses, where you needed the weight capacity for the engine, and maybe for better traction.
Modern buses have used pusher engines for a long time, which I think is why we see dual rear axles on them.
Plus tire tech has changed so dramatically even since the 80's that we no longer need more wheels to have sufficient traction for turning.
But this is a lot of supposition on my part. There's probably quite a bit of "cool factor" in this show car.
