Rohloff built-in security!
Today a guy tried to steal my bike while it was parked against the wall of the sandwich shop I stop at every morning. While I was inside and waiting in the queue, he snatched the bike, jumped on and tried to race off with it, but I saw this happening and ran out of the shop to find him on the ground, scrambling to his feet before running off! Reason? Every time I get off the bike knowing that I'll be stepping away from it for even a minute, I turn the Rohloff shifter to 1st gear. It's been a habit for the last two years, but today's the first time I saw a demonstration of the benefit! If you use a Rohloff, I'd recommend it as a good habit.
