Motor racing circuit for Ebbw Vale

Developer are trying to raise £250 million to build a motor racing circuit near Ebbw Vale in south Wales, now from what I'm hearing all is not quite as clear as it should be behind the scenes.

Frankly I'm baffled by the location, putting a world class racing circuit at Ebbw Vale seems a strange choice.  Now don't get me wrong, Ebbw Vale could do with all the employment it can get, but it's being claimed that 7.000 jobs will be created.... WTF?   What racing circuit in the world has 7,000 staff?  the answer is none! A few hundred is more lightly, and even building the circuit..... 
Going back a bit the garden festival went to Ebbw Vale, I heard the same sort of rubbish mentioned then, I was working for a newspaper at the time and checked up on the figures, not only was there a lot less people thats initially claimed but worse, they were nearly all from outside Wales, the vast majority then were from Bristol.

Another point thats been overlooked is Wales already has several motor racing circuits, the thing they have in common is very little use, and not a hell of a lot of paying visitors.

But for me the biggest reasons for not building a circuit at Ebbw Vale are ,  A the road access, the heads of the valley road has got better, but it's still closed due to serious accidents all too often. it's also not very big and a good way to Ebbw Vale from the nearest Motorway.  You have the A465 from Neath or the A470 from more or less Cardiff, both a good distances from the motorway, and both suffer very heavy traffic at peak times (especially the A470).

The weather is another factor not considered, Ebbw Vale is quite high up, they got a fair bit of fog and rain compared to say Cardiff, Ebbw also gets a lot of snow/ice, they often have it when pretty much everything the other side of Hirwaun is free of it.

Like I said earlier, don't think I'm bashing the people of Ebbw Vale, on the contrary I had the pleasure of working there for several years, a nicer more welcoming friendly group of people would be hard to find.  The areas been depressed for a long time and any jobs would be welcome, sadly I suspect this project won't bing many jobs but will cost the local government/council a fortune that could be better spent than making someone pipe dream into a new white elephant.
