I start on red,
I stop on green;
Don't care about yellow,
if ever seen.
Who or what am I?
A golfer
Explanation:
You start on the red tees and finish on the green. You rarely see yellow because golf courses are well taken care of and don't normally have yellow grass.
Could be:
Battery charging
though some chargers use yellow instead of red ;)
Pedestrian
Explanation:
At a pedestrian crossing, the pedestrian starts when it's red for the cars, stops when it's green for the cars, and (the dodgy part of the explanation) doesn't care about yellow as most cars stop when it's yellow?
Thinking outside the box:
An entrepreneur.
I start on red,
An entrepreneur starts in the red to invest into a venture.
I stop on green;
When the venture makes a profit or when it is bought out, the entrepreneur makes his "green" and (often) moves on to something else.
Don't care about yellow,
An entrepreneur doesn't care about yellow.
if ever seen.
If the "green" is ever seen. Often an entrepreneur will fail.
You are the Monopoly car.
I start on red,
The car can start on one of the red properties (Kentucky Ave, Indiana Ave, Illinois Ave).
I stop on green;
When rolling and moving from the red properties, often a player will land on one of the green properties (Pacific Ave, North Carolina Ave, Pennsylvania Ave).
Don't care about yellow,
if ever seen.
If the player gets a roll that will take them from red to green, they must pass the yellow properties (Atlantic Ave, Ventor Ave, Marvin Gardens). In Monopoly, a player can only interact with the properties they land on, so in this case the player wouldn't care about the yellow properties because they are just passing by and don't get to see and purchase them.
Cross traffic.
Explanation:
When my light turns red, they start moving. When my light turns green, they have stopped. They don't seem to care about my light when it turns yellow -- as they really don't ever see it (unless turning).
Maybe, but not likely, you are a...
Javelin Thrower?
You start on the red...
clay. Most places (not sure what the official term is) use red clay for javelin throwers. As seen here:
You stop on the green...
While technically, you stop before the green grass, javelin throwers must stop before it otherwise it is a rules violation.
You don't care about the yellow, if ever seen
Yellow is only sometimes seen on the javelin itself or the uniform. It is sometimes seen on the track as well and may be used as a marker. Either way, it won't be too important, and is rarely seen.
Well, I tried :)
The brake pedal of a car. You engage it when the light turns red, disengage when it turns green, and hit the gas when it turns yellow!
You're
the winter cold. You start when leaves are red, you stop when leaves are green.
One possibility:
A perfect programmer using Eclipse
Because...
Doesn't stop on red errors because he knows what he is doing,
Always reads the green comments,
Doesn't care about yellow because he rarely gets a warning, but if he does, he knows how to fix it without even reading.
Another possibility:
A scared guy who forgot it was St. Patrick's Day
Because...
He runs when he sees blood (from pinches)
He stops when he sees people are wearing green
Yellow shirts aren't worth his time.
An anti-golfer cyclist on his/her/its way to the putting green.
Explanation:
I start on red:
Cyclists are always go straight through red lights and start life as a red socialist, one example of this is the fact that they refuse to just work hard like normal people and get a car.
I stop on green:
Trivial, stopping when they get on the putting green, destroying the surface with their tyres and frightening the animals with their Lycra clad bodies.
Don't care about yellow, if ever seen:
Don't care about the fact that they are perceived as yellow-bellies by others, given that they are too cowardly to cycle on busy roads junctions and instead ride on foot paths, which results in frightened dogs and the scaring of the elderly with their angry, sweaty, smelly, Lycra covered bodies.

Clearly satirical.

to use spoilers. Even if it satirical, who knows? Either way, it's just common practice.
