I believe Disney's intent is to keep folk moving. They don't want any of us waiting at the bus stops for very long, as idle feet = idle wallets. Disney also doesn't want us to build up animosity toward their systems, it won't help to keep you as a returning guest. The changes they've made to improve the technology seem to have helped, even if we did have that one 50 minute wait to get over to AK from Kidani last summer (could have walked it far faster had there been a path).
I think we have the winner here! Looking at it seriously from the best interests of Disney - they don't want you at that bus stop. Are there problems from time to time, sure - but I commute to work 5 days a week - I want to PARK the car at WDW and let someone else drive.
