HGW,
The driving has been reported numerous times in the past, both verbally and in writing to your management. But thats water under the bridge.
Beware, SACL are on the warpath about driving, especially in the baggage area at the interenational and domestic terminals. That includes T2.
It will be crowded under T2, drive slowly or someone will get hurt.
Yes, I am very close to the action.
