Seriously? Oh good God, the humanity... people have to stand on a bus!!!!! Now, before I continue, this is not aimed at those people who personally choose not to stand on a particular bus trip. Just step to the side and let the people behind who want to get on the bus continue on. (In fact, I saw that being done several times on my WDW trip just this past weekend. One of those times, my family was the next group in line and we, along with two other Guests, managed to squeeze on because the group ahead of us wanted to wait for the next bus. There is definitely no problem here at all.)
However, to whine on and on about having passengers stand on any bus at all every couple of posts just gets a little old. Now, as the overwhelming majority of those posts come from Americans, I do understand that there is a cultural difference in play. For most Americans, the use of Disney Transport will probably be their only experience with public transport as it is not anywhere near as widespread as in other parts of the world. I do live in the US, but I wasn't born here and I have lived abroad for a short period of time during college, so, to me, public transport is nothing novel. I can tell you that, from my experience, people stand on buses, trains, and boats all over the world. Just a few weeks ago, I rode on a packed bus in Geneva after going to a festival and I am pretty sure that I turned out alright after that. Of course, some places, like India, go a little crazy and people are hanging on to the sides of trains and buses (certainly an experience to remember!), but we aren't talking about it being at that level at WDW. No matter what city I was in, someone (sometimes yours truly) had to stand while riding a bus at some point. As the buses are designed for standees, Disney Transport is no different. Plus, I am sure that everyone has seen news stories about accidents that involved motor coaches (which are not meant for standees and have seat belts) and a number of passenger deaths, and in which standing passengers wasn't an issue.
Plus, if the impractical idea of having everyone seated and seatbelted on a transit bus were to be adopted, why stop there? Why not have everyone seated and wearing a seatbelt while riding the subway? After all, there have been crashes of trains, too. I was on a train that derailed once (in India, where safety comes first

) and I am pretty sure that would have not made a difference is saving lives if the derailment had happened at high speed, rather than the 20 mph or so that the train was doing, as it was in an urban high-traffic rail area.
Anyway, back to the point. Disney Transport buses (all three models) are designated for a capacity of 72 passengers. Although a bus may be packed in
your opinion, it does not mean that it is over capacity. In fact, rarely, if ever, have I seen a bus reach a Signal 72 (WDW code for a full bus) by actually having that number of passengers onboard. When I worked for Parking & Transportation Services at Rutgers University, it was not uncommon to report the RTS buses (the old ones with steps) as having 90 passengers onboard because there is no prohibition there against standing in the rear stepwell and students would simply squeeze themselves into any available spot to get to class on time. (RU also has a whole bunch of Novabus LFS models, the low-floor buses with the rounded front and window in the back, in the fleet, but, as those came in after I was done there, I can't make any comparisons in capacity between the buses of that model at WDW and RU.) As long as transit buses are approved for standees, there will be people standing on them, including at WDW.
