I would have to agree, revving the engine is not going to communicate hey you are fing up idiot, the horn does a better job of that. But I think she is just saying making more noise next to the car made the cager notice . But again I am sure that If I did that (in some cases) they probably would shrug and continue to move over (Some people might notice though and correct themselves). Like I said it really depends on the driver and whether they are being attentive. Loud pipes may help but do not assume they do...tis why I don't want a loud exhaust-area p quiet core for me
kkim you just had to start the war again huh lol
