Maybe he wasn't actually wanting to race you? Maybe it was just a big mis-communication.
Douchebag drivers in LA:
#1 Mercedes
#2 Lexass
#3 Random riced up cars
Different types of douchery by drivers of different cultural backgrounds. Never had any bother from Mustangs or Corvettes or any of that. Just people driving high end vehicles who have an elevated sense of entitlement, so don't need to follow the law or common sense and kids in Civics who think that a 4" exhaust tip and a plastic body kit covered in stickers makes them into racing drivers.
I never get into any pathetic hormonal coc* measuring nonsense on the road. Just not worth it.
