Probably, the biggest is that Tesla HAS been thinking about recycling. In fact, GF is build just for that. Likewise, they will be re-using a number of the cells from a 'spent' pack to run their GF, prior to recycling (which is cool).
How much does the battery cost to replace?
Unknown since it is not known how soon one needs to replace it. With the first round of the batteries in the MS (i.e. 2012 version), it appears that somewhere around 200-250K miles, is when the battery pack will be around 85% level. So most ppl think that it new packs will be needed around 2020-2022. At that point, it might costs 5K for a change.
Of course, with 200-250K miles on an ICE car, you will most likely have to rebuild the engine, along with all of that nasty maintenance.
It isn't a problem, and the installer need take no special measures. The system's loader restricts the search path for dynamic libraries when it's running with elevated privileges so you don't accidentally run an infected library in some random location (for example, the download directory).
There are also techniques available to load libraries from a specific path after the program starts rather than at load time. You can use that to choose a specific full path to the exact library you want to load and it still counts as dynamic linking.
But TFA DID. It spoke of the value to the hackers in gaining control of the domain controller. That's a Windows thing.
There's no future in time travel.
