Electricity has a limited distance between connections with the wire tool...so use the same distance for the ziplines or increase it slightly to a distance that works and make sense. You need several runs off a mountain ..not just one super long one that would screw up the loading of graphics. Who would have a cable that long anyways. Off a skyscraper...go to next lowest building rooftop....rinse ...repeat.
This would be more fun and make more sense than falling all the way down onto hay bales.
Personally I could care less for any of these....but ziplines are more practical than a helicopter in a post apocalyptic world.
I would rather have resources put into wind turbines/windmills, water mills, more block types, gear boxes, etc....stuff that could actually be a possibility for survival. Most cars would be knocked out...all electronics for that matter.. from EMP bursts or something that the government would of tried to stop the infection from spreading.
The survival aspect is slowly getting erased in this game with vehicles, especially with the gyrocopter.
Imo
