Again, if someone goes to the expense of procuring
ECV, I have no doubts that they need it, but believe me, I have heard people talk about renting wheelchairs to get to the front of the line. I have seen it. I realize that there are all kinds of disabilities, respiratory, cardiac, arthritis, etc that aren't clearly visable to the casual observer but it is naive to think that abuse doesn't happen on a frequent basis.
This is a list of Mainstream Attractions from the WDW website.
Mainstream Lines are lines that are accessible and people with wheelchairs and
ECVs wait in the same line with everyone else.

As I pointed out back a few pages, someone in a Mainstream Line , like the Nemo ride at Epcot, waits in the same line with everyone else. If they don't need a wheelchair accessible car, they will get into the next clamshell that comes along - just like everyone else.
But, if they have to wait for the accessible clamshell, they end up letting about 37 people ahead of them for each minute they wait (assuming the ride capacity is 2200 people per hour as Wikipedica lists).
If we waited for 5 minutes at the boarding area, that means we let 183 people ahead of us because they could board the next clamshell that came along and we could not.
The same thing happens in rides like Buzz Lightyear or Imagination, where people with wheelchairs board at the exit - but they
are routed to the exit just before the line gets to the regular boarding area. For people who can get out of their wheelchair and board a regular car, they will get on in about the same amount of time as a non-disabled guest.
That often means that while we are at the exit waiting for the wheelchair car, we see the people who were in line right before us in the regular line getting off while we are still waiting.
