I'm sure the policy has not changed because the
ECV companies caution not to ride on their products in a moving vehicle. Disney would not make a policy encouraging people to do something the company warns about.
This is a link to the general Pride Mobility Owners Manual (most of the rental companies use Pride Mobility products).

Unoccupied Motor Vehicle Transport
We recommend that you do not remain seated in your
scooter while traveling in a motor vehicle. The scooter should be stowed in the trunk of a car or in the back of a truck or van with batteries removed and/or properly secured. In addition, all removable scooter parts, including the armrests, seat, and shrouds, should be removed and/or properly secured during motor vehicle transport.
WARNING! The scooter user should transfer into the motor vehicle seat and use the vehicle- installed restraint system if and whenever feasible. The scooter user should never sit on the scooter while it is in a moving vehicle.
WARNING! Although your scooter may be equipped with a positioning belt, this belt is not designed to provide proper restraint during motor vehicle transport. Anyone traveling in a motor vehicle should be properly secured in the motor vehicle seat with safety belts fastened securely. End Quote
The
ECVs are fastened down with the tie down straps whether someone is riding on it on the bus or not.
The tiedown is to keep it from tipping over; tipping is especially a potential problem with the 3 wheeled ECVs because anything with 3 wheels can tip more easily. They can tip even if empty, but they are more 'top heavy' and likely to tip if someone is sitting on the seat.
(In fact, at least one DIS poster - lovetoscrap - has tipped when she was riding on an ECV on the bus.
Strapping it down doesn't make it safe for someone to ride on the ECV, although some people do still ride on it.
There are signs on the bus that suggest ECV users transfer to a bus seat. If they are visible all the time, they are when the seat is folded up to make the wheelchair/ECV seat.
Some bus drivers are more proactive about suggesting transferring to a seat. Some don't say anything and leave it up to the ECV user, especially if the bus will be full. I have personally heard drivers suggest people transfer to a bus seat; some did and others refused.
