There are, unfortunately, a large number of rude and inconsiderate players who seem either unable or unwilling to dismount their speeders/hoverbikes while at the Galactic Trade Network Kiosks. These people seem completely oblivious to the fact that those mounts take up a LARGE amount of space and, in some cases, they park so that they cover the kiosk and make it difficult for more mature, responsible players to use them. I have even seen players run up to the kiosk on foot then mount their speeder and sit there. Do these people think we're impressed with their mounts or what? - I, for one, am not in the least little bit impressed and see absolutely no legitimate reason for these players to be doing this.
The area on the fleets where the kiosks are located could very easily be turned into "No Fly" zones where players are forced to dismount. The "construction" in those areas would very easily accommodate some sort of partitioning or sectioning that could be set up to disallow mounts.
Blizzard did this in World of Warcraft for a very good reason - can you imagine trying to use the auction house with half a dozen drakes and whatnot filling up the building?
Seriously, this is an issue that needs to be addressed.
