I live in Gojo and I'm regularly woken up in the dead of night by the sounds of cars revving and speeding off. It doesn't bother me that much as I'm pretty far off from the source and I only really notice it if I leave the window open, but I'm genuinely so curious too see if anyone else has heard this or knows more? Like where tf are they doing this and like what's the point??? Having a little race when the cops are all in bed? It's going on like clockwork every night!
Would be reassuring just to know that I'm not losing my mind!
edit: found some other people discussing it:
