Drones are extremely maneuverable, and non-volitional AI allows them to swarm: fly collaboratively and follow targets autonomously. Take the following steps to avoid/survive an attack.
Take cover. You cannot outrun a drone; however, you can put solid objects between you and them. Depending on how elaborate the drone's sensor package is, a wall between you may break contact, or it may simply force them to hover in hopes of catching a glimpse of you to resume the chase (see above).
Run quickly in a zigzag pattern. Old NVAI drones can be tricked by very fast movement when attempting to pursue, allowing you to escape unless some of the swarm is already out ahead of you. Newer drones will not be fooled, but the pattern will assist with evading incoming fire.
Move quickly into trees. Close-pursuit drones can be disabled by contact with obstructions, or may be forced into engagement range if they follow too closely. Run into a forest or other heavily wooded area where drones cannot fly easily. Note that drones may hover and be waiting when you break cover.
Remain concealed. Small drones are limited by their small batteries, and those with beam weapons must choose between maintaining a target and firing their weapons. If you can stay hidden, you may be able to outlast them. Larger military or corporate drones can operate for days and switch out pursuers as needed, but can only track targets they can actually locate – see the general tips on evasion, above.
Use darkness. Drone cameras are not equipped to follow targets they cannot see, and usually (at least for law enforcement and military applications) require visual identification or confirmation in order to engage weaponry. Sneak away after dark, preferably wearing an evasion suit to block other sensors.
Knock them out of the sky. Civilian drones that follow too closely can be neutralized by simply striking them out of the air, while armed drones can be picked off from cover or targeted by point defense systems assuming you can reach a safe place to return fire from.
Do not assume you are safe on a windy day. High-quality drones have effective stabilization mechanisms and can fly in high winds.
Most flying drones cannot operate in water, so diving under the surface and swimming away may allow you to escape. The drones may hover and reacquire you upon resurfacing, however.
