In fairness, drop bars are not the only way to get multiple hand positions.

Just adding bar ends to a flat bar can make a big difference and replacing flat bars with Surly Open, FSA Metropolitan or Jones H bars can also be a nice upgrade without resorting to drops.

I don't ever use drop bars but its not because of visibility, it's because I mainly ride IGH hubs and shifters for those do not readily fit on drops without expensive upgrades, especially Rohloff shifters.
