Snakes, like most wild creatures, just don't wander around for the fun of it. Those sort of behaviors were selected against millenia ago.
Snakes in the wild are faced with a dilemna. They need food and water, but if they wander around during the day, the get killed by predators. So snakes are reclusive and nocturnal where that is available. When they are adequately fed and their needs are being met, they tend to spend their time hiding. It is safer that way. When I see a snake cruising back and forth in a cage, I infer that the snake is in someway uncomfortable, be that because of lack of food, water, proper hiding place, proper temperatures, etc.
There are some snakes that are less reclusive than others. My western hogs tend not to use any sort of hide box or to bury themselves. So, most of the time they are visible. Of course, they are sleeping, but I can at least see them sleeping.
Some arboreal snakes will sleep during the day in a visible position on a branch, but they aren't cruising around all day. I have kept "really active" snakes, like coachwhips, before and invariably, when they are well fed, they spend the day in their hide boxes.
If you want a pet that is always active in the day and willing to interact with you when you want it to, you should consider a social animal like a dog.
