Nothing against ECVs, but they do take a considerable amount of time to get on and get strapped in. Add to that the rest of the party, you now have a long line of non-
ECV users who have waited a while who won't get a seat (since ECV gets on first), and even possibly won't get on at all and, well, that's a source of frustration. Everyone stays mum about it though because who complains about someone that needs the ECV? How crass would that be? It just seems like there is a better way, even if that involves accommodating them with something like a Minie Van that everyone else would pay a premium for. I really have no problem with that.
