We have the same stuff down here,too.. Fart can exhausts,etc.. Blow off valves,hair dryers,et al.. We call them sneezing jappas.. Yes,they are quick,,but some,not as quick as they think.. we have an annual meeting,at one of the dragstrips,,which is commonly called ''Hamburger v Rice''The first two years,,the wiley old hotrodders won,,cos the jappa kids didn't know a great deal about quick reaction times.. The third year,they got the drop on the old guys,,but since then,,it's been a hard road for them.. They get some wins,,but even with good pairing between the two factions,,we still get them mostly..
