Is this the future of public transport in south east Wales? Will it ever transfer from a test track in Cardiff Bay to the city's streets?
The answer is no.
A decision by the Welsh Assembly in January 2003 to withdraw £8m of financial backing for the scheme effectively shelved the project to the dismay of Cardiff council.

However, the report makes no reference to the system the Assembly had previously supported.
