Good Courteous Drivers: Is that too much to ask?

Is it too much to ask for people to be good courteous drivers? All I want is for people to not be reckless and endanger others' lives and to have some common courtesy for other drivers. All I want is for them to stay in their own lanes and when changing lanes to use their blinker and look before changing. All I want is for them to go the speed limit; if they must go faster then they can surely wait for a passing zone or lane and wait their turn when in a line of people; if they must go slower then they can surely move over in passing lanes and not speed up when others try to pass them. All I want is for people to read and follow traffic signs like stopping, yielding, or road construction signs. All I want is for people to follow traffic laws like using a blinker and not tailgating. All I want is for people to not be stupid when driving through construction and if they just can't figure it out, pull over and let somebody else lead the way. Is that too much to ask? Are good courteous drivers just few and far between? I hope not.
