Voting makes absolute rational sense, what are you talking about. It's just that it makes sense in aggregate, but for that to make sense everybody must do their part.
The chance of one vote being the difference between a tie and a win for a candidate has been approximately zero. And in the extremely rare times when there has been such a one vote difference, there have been re-counts that conclude with a margin that is larger than one vote [0][1].
Mathematically/statistically this makes intuitive sense. One might ask: what's the chance that a vote ends in a tie when there are 10, 100, 100,000... 10 million voters? As the voting pool increases, the chance decreases.
The most common objection is along the lines of, "if everyone decided not to vote because their vote didn't matter, then no one would vote!" Yep, that's correct... but that doesn't describe reality: clearly people vote a lot.
Voting because one enjoys it, gets satisfaction of some sort from it, feels that they are doing their "civic duty" and discharging a responsibility, etc... that's fine. But don't vote because you think you're gonna change the outcome.

This is like asking, "if pigs could fly, what happens?" -> all sorts of things... but pigs can't fly.
"if nobody votes..." is a hypothetical that has never been true because people DO vote. I don't know of a good reason to believe they'll stop voting. Obviously the futility of voting to change the election outcome isn't stopping them so far.
I don’t understand that. The fewer people vote, the more impact your vote has, so the more sense it makes to vote (up to a limit, of course. If too few people vote, revolution gray be around the corner)
Try to do an expected value analysis of your vote. Say the difference between your candidate winning or losing is worth 1000 USD. Multiply that by the odds that your vote will cause them to win. Take that very small number and see if you'd drive 2 minutes for that or just calculate if the lead used up on the pencil is worth that.
