This has changed. Rode today with wheelchair, they make you go through the regular queue then board you straight after the preshow bit with your party

Thanks for popping this up - I only finished doing the Mainstream Access for 2 parks. I meant to complete it for all the parks, but got busy (actually, in September, we were getting ready to go to WDW and I never finished entering the information).
The access for wheelchairs has always been thru the regular (or Fastpass queue with a Fastpass), so it is a Mainstream Line.
The Guidemap lists it as Mainstream for
ECVs.
It's always possible that the CM at the attraction
could send someone thru another access with a wheelchair. Sometimes it's for reasons related to the individual - like they have a larger than usual
ECV or an ECV plus a Service Dog.
Sometimes it's for ride related reasons. At Test Track, loading is on one side of the track and exiting is on the other side. This means that wheelchairs and ECVs need to somehow get over the track. If the guest loads in the regular loading area, the CMs will take the wheelchair or ECV up in an elevator to get over the track. Then, the ECV or wheelchair is taken down to the other side of the track.
We need to board at seat belt check area, so DD goes up in the elevator in her wheelchair. That means we see the whole process, but anyone who is boarding at the regular area won't see that and may not know how their wheelchair gets around to the exit. Some wheelchairs/ECVs may be larger and it may be easier to have those guests enter thru the exit.
If you just go up the exit without clearance from a CM, the CMs at the exit are likely to tell you that you need to enter thru the regular queue.
Test Track is an attraction that Service Dogs are not allowed to ride. So, with a SD, it makes sense for them to enter at the exit. That way, one of their party will be able to hold the dog for the SD handler while the handler rides and then they can switch off.
I don't have time right now to add the information for the other parks later this week.
