No it was never full so no big issue but we walk past this way every game and can confirm there were cars on there. Used to see a lot of vans with big satellite dishes on top (which is why I thought it was just for the media) but more recently it's been just cars. The arena seems to be on the land between the canal and Forge Lane and that land is split in two by a row of hedge in the middle so it can appear as though it's two bits of land. Also I don't know if the bridge over the canal is usable for vehicles so it may be overspill use from the car park on the other side of the canal/tram. Gibbon Street still is google-mapped as two car park entrances into this land (one off Forge Ln and the other off ATW). Obviously that road used to run over the bridge.
