I mean we have boats, aquazips and rocketships so I don't see problem other than that going to work might be bit iffy
but we could at least have helicopter pick up our sims for level 10 jobs
since I mean if we can have alien abduction and rocketships shouldn't that be possible just as easily?
the cars themselves could work similar to boats +rocketships
meaning you can build them, upgrade them, sit in them, woohoo in them, drive them in routed areas and store them wherever on your lot
id also really love one car optimized world where driving would really make sense for this purpose
and oasis springs could be updated too since I don't see why not
