Where did you get those maps from?

You are able to DRIVE something in the HL-engine? This is not Battlefield, am I right? I only know the railway in the Mesa station.

And: I think, Stefan has really so many other probs with Bomb setting, Bomb finding, Nodes system etc. and as student he, as I think, has much work on the university, so that this funny "Drive"-task will have very low prio...
