[ELI5] why do spiders tend to build webs in the same places when they get destroyed every day?

For some more context, I park my car under a pine tree every day. Every morning when I leave for work there's always a couple of spiderwebs going from my car to the tree. Naturally I destroy them. Why do spiders keep insisting on building webs in places when they're consistently being destroyed?

During the time right before dawn to right after dawn, nocturnal insects head in to sleep, while diurnal insects wake up and head out to do... insect things. Spiders often set their webs to catch this transitioning prey.

After the sun has risen, the spider has gotten all the food he expects to catch from this web, has had a good meal, and has stashed any extra in a safe place.

Now you come along and destroy his webs. No big thing, mealtime is over, he's well fed and happy.

Next night, he spins his web to catch another breakfast.

tl;dr: Spider has gotten use out of it, it's a good spot, so doesn't care if it got destroyed during the day.
