> Projects like this aren't happening in the US because there is no political will. If you are going to have bus lanes you need to have enforcement. Buses should have cameras ticketing other vehicles in the bus lanes. Turn lanes should not merge into bus lanes, drivers should be forced to wait for a green arrow to make a turn across the bus lane.

I can probably speak to a bit of this as I am from Adelaide... and have also driven in the USA before.

The driver mentality in Adelaide, compared to USA (and even the eastern cities of Australia like sydney / melbourne), is a lot more laid back. Adelaide feels more like a really large country town rather than a city. Speeding isn't that common (still happens but its not every single person) & cutting people off doesnt happen as much in america.

The O-bahn, is mostly designed for only specific public transport busses. About once or twice a year a car or mini bus (usually driven by tourists) gets stuck on it and has to be lifted off. They recently did an extension to connect it into the city via a dedicated bus lane that turns into a tunnel. I drive along this stretch of road every day, and I think i see about 1 or 2 people a month driving in the dedicated bus lane, usually because they didn't know what was going on rather than doing it on purpose.

The O-bahn services about 26% of the workers in Adelaide City.
