The roar of supercars and motorcycles

Don't the riders find it noisy too?
Wow, it's a mess even at this hour..
I saw some people at Jamsugyo Bridge taking photos of these people with DSLRs.
If they were women, it would feel like they were being treated like groupies..
But since they are men, I don't even know what to say..
People coming and going, making deafening noises even at 1 or 2 AM.
I wonder what's going on in their heads.
But since it happens so often now...
It's giving me a headache.
I had to come in with the windows closed.
