Are these guys street racers?
I don't know anything about street racing, but there's this group of guys that have these cars with really loud engines that pop and make random explosion sounds. They meet at this industrial park roundabout late at night and drive their cars around for a short time before dispersing. Their engines are so loud that I can actually hear when they get together and race around, and I live 5 miles away from that location.
The only reason I know where they get together is because late one evening on the 4th of July a few years back I happened to be parked on the side of the road in the industrial park facing the roundabout, while visiting my boyfriend who had just gotten off of work after staying late. We watched these guys race around with fireworks going off around/from their cars while someone was recording them. It was actually pretty cool.
Then some of them left the roundabout, drove in our direction, and started drifting really close to my car. All of that happened within like a span of maybe 5-10 minutes before they all drove away. I also had my son with me who was 5 at the time and he thought the whole thing was super cool and waved at them as they all drove off.
Edit: I wanted to add that I have been trying to find the video online, if they posted it. Fireworks + drifting is apparently a popular thing, but if they did record them drifting close to my car I'll know right away it's the right video because my car is a purple 2010 Scion XD.
