When i was out exploring i found Joe Builder on the Hypergrid and he told me that he got some vehicles on his grid and big areas to drive them. Joe is a builder in all sense of the word. Lost world have big areas connected with the hypergrid.
I visited a wasteland. Drove a truck, killed some zombies or something. Visited like Jurassic park, a space station and a underwater world. I think there are much more but not everything is up all the time.
Joe told me he is using older Opensim and ODE and it worked good.
Dont forget to take a tour on the Jetski.
