I wish. Unfortunately, even though that is the better option, it is more risky: everyone (meaning businesses in this case) already pay taxes to support roads, thus using them, even if it's less efficient, is "free". Plus, all businesses are connected to a road. Compared to building and maintaining infrastructure for a rail network, where you're limited to customers you've built rail to. So I'd wager the "last mile" would likely continue to be truck based, even if rail use exploded.
To be fair though, the rail networks here in North America are seen as the most developed freight networks in the world (I wish we had more passenger service though; my daily commute to KU and back is a pain): 2863 Gt-km (NA), 2451 (China), 2351 (Russia), vs 391 (EU).
