Here are some photos of the AVAs operating in Oslo Norway in 2019.
It is in a tourist bus loading area so it’s not as dangerous as it looks. Everything moves at about 15 miles per hour. I don’t remember if they had automatic ramps or not. I suspect (but don’t tell the Health and Safety guy) that at 15 m/h or 25 k/h tying a power chair down may not be necessary. You would fly out of the chair before it lost traction. 😉
In an area like this they may not be required to meet ‘Highway Traffic Act’ requirements.
