I have a whole post on that pic above coming up in the next few weeks. Man I wish they made models of this stuff!
There's some absolutely phenomenal multi-wheeled Syd Mead vehicles over here as well. I particularly like that Ark II-style conveyance with the humungous mirrored-glass cockpit... just perfect for those sightseeing trips outside the arcology.
Oooh, the VEX is a nice ATV for Traveller. :-)
