Final number bets?

It feels like every time I play roulette, there’s that moment where a couple of players start dumping chips on single numbers in the last seconds. I’ve always been more of a systems person, looking for logic where maybe there’s none, so this kind of all-in chaos move confuses me. Is it more about chasing the rush or is there some angle I’m not seeing?

For anyone who bets single numbers at the end - what’s going through your head? I see it often, especially online where you can change your mind right up to the spin.
