Henrik does want to have wagons it's just unlikely to be in game anytime soon but they should be slower than riding on horseback. Auto pathing is not something I would think fits this game or is in SV's ability to program.
I do think their should be "autopathing" along the roads similar to the Witcher where your horse just follows the road. Nothing like autopath to this town but to allow you to have hands off the keyboard as you travel along a road on your horse or wagon.
