That's great. (although as TDD indicates we're kind of retroactively projecting the Bronze-Age Neal Addams GA look, back onto 66)
Still, just imagine if along with the 66 Green Hornet crossover and spin-off they'd done a parallel Green Arrow spin-off show at the time.
Further, imagine Barris having designed an Arrow-Car, would have been legendary.
Or the Winfield designed "Reactor Mach II" car, aka Kirk's Jupiter 8 used as catwoman's catmobile, stripped down of it's campier cat elements, would have worked great
.
Or for a more retro version they could have straight re-purposed the Golden Arrow land speed racer.
