Gas odorant

Smelly tipoff
  [vote for,

Emissions control stations test car emissions to see if too many pollutants are being spewed out. Sometimes it is obvious that this is the case, but sometimes it is subtle.

Natural gas has an odorant included to tip folks off that unburned natural gas is leaking. The odorant is broken down if the gas is burned. I propose that a similar odorant be added to gasoline. This would be a strong, strange odor (maybe patchoulli) which would be completely destroyed in a healthy hengine. Engines with too many bad emissions would likewise emit some unburned odorant, tipping off the owner that there was a problem.

A similar odorant could be added to brake pads, but just because burning brakes smell so dang bad.

       Yeah, and while you're at it, leave the gasoline alone too, I love that smell!

       a visual warning would be good enough. An odor would just anniy other drivers

       For a visual warning, I suggest combat clowns paratooping on top of the offending vehicle.

       Patchouli is a very strong fragrant oil often overused by many who fit the "Brooklyinite Italian" stereotype. So, instead of smelling like smog, freeways would smell like little italy, minus the lasagna.

       Out here on the left coast, patchouli is used by those we used to call hippies, then we called throwbacks, and now we just step over them on the sidewalk if we happen to be unfortunate enough to end up walking down Haight St. As Robert Mailer Anderson said in the disclaimer to his book 'Boonville' (the best part--the rest of the book is pretty lame--don't bother, I wish I hadn't) "As for the hippies in the county who may be upset at the depiction of hippies, I say, 'Tough shit, hippie.' Anyone willing to identify themselves as a hippie here in the 21st century has their head up their ass and gets what they deserve."

       Patchouli: A small southeast Asian shrub (Pogostemon cablin) in the mint family, having leaves that yield a fragrant oil used in the manufacture of perfumes.
