The trishaw drivers do it hard. We did not use any until we decided that we might catch a ferry across the river. We were told that we couldn't go with the local population and so because there were a large number of trishaw drivers waiting for customers near the ferry area we decided that it would be a different way to see the city.
Trishaw drivers are restricted in terms of where they can ride so we just asked them to take us down to the river and show us a couple of other places. For US$1.50 they took us along Strand Road and down to the river, then to Kheng Hock Keong (Chinese temple) and then Shwe Dagon Pagoda Road where we then proceeded to Bogyoke Markets on foot.
At some places specially downtown you will find rickshaws.. or more literally trishaws.
These are again not found in most parts of the world and the closest in approximation to what we have in India and also.. I would admit some other Asian countries including China..(Beijing in particular)
The difference in here is that the rider sits right beside the passenger.
I didn't find it in all places.. infact the only two places where I found them were near to the river-- close to Sule Pagoda south of the city and near the Railway station.
A trishaw ride can be fun, especially if not in the heat of the day. You can also get some good photo's during the ride (hint here - use action mode on your camera)
