tailpipe

The stuff coming out the tailpipe is orders of magnitude worse than after it's warmed up.

Bad air-fuel ratios also cause lots of pollution due to unburned fuel being sent out the tailpipe.

It means your car is not running optimally; generally it means it is polluting more than it should due to O2 sensor failure or backpressure from tailpipe.

Its one of the least objectionable things a car could spray (dribble?) out the tailpipe.

They produce no emissions (other than wear on tires and brake pads) at the tailpipe.

It's in the same ballpark as the amount of water vapor that comes out of the tailpipe of an internal combustion engine.

Somehow I doubt we'll see any automobile pulling a trailer hooked to the tailpipe to collect all the exhaust!

With ICE engines, you are producing CO2 out the tailpipe, in the refining process, the transport, etc.

I do not take any pharmaceuticals and do not smoke tailpipe exhaust commuting daily(which is worse?).

But theirs is as nothing to the whiff from a tailpipe.

If you combine the tailpipe emissions of every car on Earth, that accounts for less atmospheric pollution than just 16-24 gigantic ship engines, burning bunker fuel.

When I first read this I pictured a spray of dust out the tailpipe.

Vehicles without OBD-II and "other" vehicles use a tailpipe probe to report on exhaust gases.

The keyword for the problem you're talking about is the "long tailpipe theory." [1] I was just reading Wait But Why's article [2], which concluded that the overall greenhouse impact will still be lessened by using electric cars over internal combustion.

"the only byproduct is water, which exits through the tailpipe" How much water are we talking about and what effect is this going to have on a highway in the north in winter?

Tailpipe emissions are much worse in urban than rural areas because there are more people to breathe them in.
