I always get this inner feeling of shame whenever a rider does exactly that... or is revving at lights or worse yet, pulling stunts. Tell me about it! I ride with two older folks sometimes. One is about 62 years old riding a 170hp ZX14 sport bike and the other looks like a Harley rider (pardon the loose term), all out American BA but always riding his sport bike on a full suit! Well said. I once installed the typical FIAMM freeway blaster horn on my ride, but it just doesn't sound as loud as a throttle blip. Heck, finding the darn tiny horn button will sometimes take me more time than a blip.
