This is really mad.
The barriers where a bad idea, why they needed them no one knows.
Surley someone employed to move on cars from the area would be sufficent. Oh then again no body moves any cars on from Heathrow Terminal 1, 2 and 3 not even the Traffic warden do this.Today I queued from the m23 to the terminal to get onto to the ramp to drop my FO off today just to find cars parked outside on dropping zones.
At Southamptom they had a good way of moving traffic, a Car Wheel clamp on a trolley and was pushed slowly towards you if you not moved.
