How common are lay-bys?

I’m American, but I read a lot of British books. It seems like in every other one, someone is pulling off into a lay-by at some point. I had to Google what that is, because it isn’t really something we have here except in special circumstances, like a scenic overlook or pullouts in mountainous areas, etc. What is the reason behind them? Is it because the roads are smaller and have fewer opportunities for passing, or are they used on roads with no shoulder, etc.? And how common are they? I’m guessing they’re on more rural roads, but are they on highways, or only smaller country roads? And about how many miles would you have to go between lay-bys? Thanks for helping me understand this admittedly dull topic!
