I used to keep my Zorki IV in the glove box of my truck, using it as an all-around, readily-accessible camera. No need to worry about batteries dying (especially in the cold weather), and the shutter speeds don't seem to be much affected by climate. And if the vehicle got broken into and the camera stolen (luckily that never happened), no great loss.
I found it a great exercise for one's skills to learn to meter by eye. The Zorki seems to have came up with a high percentage of "good" shots; perhaps the simplicity of the mechanical design, coupled with the see-through viewfinder, makes the camera transparent to the picture-taking process.
For shooting with B/W film, you can help yourself by learning to do semi-stand (or compensating) development. This will help to somewhat even out exposure differences between one frame and the next, which can easily happen when your exposures are estimated.
One tip to operating the Zorki: don't attempt to change the shutter speed setting unless you've first cocked the shutter. This is rule #1 with this camera!
