Here's one: How to deal with the police. Their work is boring and it's not unusual for them to go long stretches of time without being paid. They see you coming up the road-- They're curious and you look interesting. They motion for you to pull over and unless you've managed to get so close that you can plausibly claim you didn't see the baton waving you'd better obey them.
The hack: For goodness sake don't sit their dumbly and wait for them to speak up! If you do they'll have to justify pulling you over. "Document!", and you're screwed. The next thirty minutes are spent going through your papers and your belongings while they look for any pretense to hit you up for a fine/bribe. Yes, it's corrupt, but understand that is the only way of life for them. Empathy and understanding will get you much further than casting judgment.
Be the first to speak. Raise your helmet visor, smile and ask for help of some kind. Even something as simple as, "Skolka kilometer Volgograd?" will do. When they answer, nod, smile, shake their hand and say, "Speciba."
There's a 75% chance you're done and you can go on your way. The remaining 25% involves a longer conversation with limited English (and compliment them on their English no matter what) and pointing out your route on a map and where you're going. They may offer you a drink or to share a meal. Feel free to do so if you have time.
I never once paid a bribe which must be some kind of record.
