This video is actually an advertisement, though it's not obvious - as with so many ads - that it's an ad until near the end.
It has a nice humour to it.
It was made for Gautrain, a modern rapid rail and bus service for Gauteng in South Africa, which opened its doors on June 8. The new service is being promoted with “Wind”, a commercial directed by Keith Rose from Velocity Films. [Thanks to Duncan Macleod for alerting me to it. Duncan has a blog where he focuses on innovative advertising.]
