^ its most likely the best we can do.

no digging and tunneling necessary.

the fact is staten is hardly a priority for new rail transit:

expanding 2nd ave & triboro rx would be priorities.

upgrading the subway signaling.

fixing the tunnels.

cuomo's new bronx mnrr stations.

finish the #@*! east river access.

even connecting lga/jfk airport airtrains and expanding 7 or L train to nj would rank above tunneling to staten island.

they are more doable too than tunneling to staten (except nj subway extensions or growing 2nd av -- i suppose those would be about the same type major level of work).
