This one is more aesthetics, but the zig-zagging Golden Road always bugged me, because the "road" on the floor was all over the place. I get the idea was to keep having the Big Prize visible throughout, and when cameras were larger, it was probably impossible to progress across the stage.
I originally thought the <$1 podium could be behind the turntable (with the ability to really bling out the start position). However, that puts the contestant at a weird angle to see the prizes (maybe it could work if they weren't right next to the turntable). With the jib camera, it seems like they could really show the "road" better as it progresses behind/in front of each door.
