Sydney Buses and vision disability

This is a photo out of the 288 in Sydney. Sydney Buses places advertising on the glass, which impairs viewability. I noticed this particularly tonight while trying to photograph the Sydney Opera House while crossing the Sydney Harbour Bridge.

Vision impaired people have a tough time, and I understand that such window films make it worse. I'm led to believe that the State government's response is that only several windows are covered- not the whole bus.

Only a non-bus-user would find this answer acceptable. We rarely get to choose where we sit; usually we take what we get. There may be reasons why a vision impaired person can't sit on the sunny side of a bus.

These style of advertisements should be phased out. It's just one more indignity for the disabled traveller.
