Lusaka has a large fleet of ubiquitous blue and white mini bus 'taxis'...they are everywhere and cause chaos on the roads, the more chaos they create the happier their drivers are...a law unto none, they cut in, swerve, break and 'U' turn without warning, they jumble their poor passengers about city like washing in a machine. I have ridden many a time in them and you appreciate being dropped off in one piece at the end of the journey...
