but why keep utilizing them in the 30's, 40's and 50's?

at some point someone had to say "Hey... lets make the doors open backwards!"

and then again, at some point someone had to say " Hey...that's stupid!"

any idea who was the first?

"Stupid"? OOPs I just realized that Saturn and many of the 4 door trucks these days use suicide doors!


hmmmmmmmmm?
