As of April this year there were two converted hangars and a car park for people working there but not much in terms of a test track other than some new Tarmac laid on the existing perimeter roads, which could have been the start of a test track.Has anyone actually seen any concrete evidence that this was a legitimate project, e.g. pictures of the car? According to the BBC article "The first cars had already been developed and were being tested" on a "£200m ... test track" and "the project employed 523 people". But none of the news articles I've seen have actually shown any evidence for this.
I doubt in 6 months they were wnywhere near completing the full test track facilities they were planning.
