Your desired vehicles/devices/objects?

Hello I hope this is the place for this... I need answers from residents I recently have stumbled upon a builder's block, and am wondering what sort of things that people desire that SL lacks.
Are there any themes, types, or specific vehicles you have not found but would like to see? Any attachments or scripted objects with functionality you have not seen? Any avatars or objects from popular culture you'd like to see replicated in SL?

Take a look at /147/1.html .

I'd like to see a vehicle that can cross sims.

I'd like to have a script/item where i could tether me and my partner together for say 50 -100 meters that would act as a bungie chord while we go exploring, so one of us could yank the other back, cause we're always getting seperated.

A dumb or useless thing? not sure, but could be fun and less of a strain on the system than teleporting to each others position.

"Honey, where are you? ... yank, oh there you are"
