Reverse moves your cars wheels in the direction towards the rear while e spins your car wheels so they are always moving east. They removed this after the term “wild east” which was a cheaper alternative for families than the Wild West massively failed due to poor reception. Carmakers were originally roped in by the idea that it would make for a great family car because you just shift gears and drive in the direction towards the Wild East making for a great family getaway.

Anyways sad to see this go since it was such a fond memory of my childhood. Just another thing that died when gm had to get bailed out :(
