Supercharging credits!
I was going to suggest this as well but hopefully won't ever need them for my 2016 S.
Hopefully I'd be able to bank them and save them up for use on my Y.
Careful what you ask for ... Tesla officially announces end of unlimited free Supercharging, new ‘Supercharging credit program’ starts in 2017
