So now that I actually had a chance to play, here are my thoughts:
I first had to wait nearly an HOUR AND A HALF to join the server. 850 slots with well over 500 people in queue, and the admins thought not to do anything? I understand that lag was pretty bad (I was there), but would it not make sense to, you know, open up a second server? The same thing could be accomplished with half the staff if they were coordinated enough, which it seems like they weren't.
After I finally connected, and waited a good 15 minutes to get through the queue, I hopped over to Salzburg and began my journey. Wasn't too bad, encountered some people here and there. Got into some traffic, which I anticipated and actually liked. Traffic was great, and the people breaking rules didn't really piss me off or anything. What DID piss me off was how poorly the event was done. It felt like a last moment "lets just direct traffic a little bit around a crash and be done." I waited in traffic for a good 30-40 minutes, only to go through the actual event for a good 10-15 seconds. And that was EXTREMELY disappointing to me.
Where were the "custom roadworks, police/border controls, fake accidents and a lot of police force showing on the route. Make sure you behave, or you might get pulled over!" we were promised? Where was the excitement? All I saw was admins in one place. I followed their directions for a good 10-15 seconds, then continued on and saw literally nothing else.
What a disappointment. Poor communication, lack of creativity, and little care for what was supposed to be a "community event".
