Went to this show as well...
The inside bit was Ok, well Ok if you were someone doing motorsport and wanted some bits n pieces... but that was really what it was advertised as.
The rallycross thing outside... well, nice effort but a couple of screwups which meant it wasn't as good as it could be:
1) The track was lined with concrete blocks but the spectators weren't given an elevated view - which meant you could only see the roofs of the cars. Unless of course you stood on the ramp from the building, which everyone did and was Ok given the weather as hardly any bugger was brave enough to go outside... Had the weather been much better it would have been pathetic.
2) The concrete barriers clearly weren't enough for H&S types, so they put in a metal barrier to keep the public back from the concrete blocks. Fair enough... but it was that 8ft high event type fencing! Why not a more normal chest height fence?!! Maybe you might think it was to stop things coming over the fence and hitting the crowd... well yes if it had been actual catch fence, but this type of fencing is held up with concrete block feet - lets put it this way, the wind was suffucient to blow it over several times so that says how much it is going to stop... No, all it did was p*ss me off.
The weather being sh*t the organisers could not help (although early December is never going to be tropical in Docklands!) but the rest, well....
