Thankfully, he was thinking about making glowstone powered minecarts before the gods tasked him with building a carriage. The initial efforts paid off when the mine carts could be operated even by non-magic wielders. Rino allowed more people into the mines to experience driving carts, and eventually, that design was used as a reference for the new cars meant to be driven on the streets.
