A couple of comments, if I may.
Over the years, I’ve consciously ‘practiced’ avoiding getting peeved at other drivers. It doesn’t always work, but it has ‘some’. I ask myself: “Self: do you ‘want’ to be angry?” And usually “self” responds with a “No!” [It also helps to ‘stay aside’ of much of the mainstream, angry, impatient, mindless culture – I do NOT watch television.]
One of my co-workers has helped me over the years, as a ‘model’, when he (when driving) will say something to the effect that “that driver drives almost as bad as I do”. This helps me to be more ‘empathetic’ and and have a more light-hearted and easy ‘tolerance’. [I actually submitted an ‘idea’ for a bumper-sticker to a company, and received some miniscule ‘royalties’ for a sticker that read: “Caution: I drive like you do!”]
I am very privileged to have municipal bus-service provided for a 25-mile interstate commute – I can avoid much of the driving that others are forced to go through. (It costs me $25 a month, and I can use the ‘pass’ around town, as well.)
I rather like to ‘stay around home’ (another ‘blessing’), and so I end up driving relatively little (and having less opportunity to ‘test’ my ‘serenity’).
The traffic around where I live (on I-5, near the Canadian border) is NOT very congested, and the drivers are, on average, better (more civil) that what I’ve experienced elsewhere. (My oldest brother, who lives in Duluth, Minnesota, will testify to this.)
However, I acknowledge most of the things that can rankle me on the road have already been mentioned. The one driver-behavior that is missing from the list (as far as I could tell) is that which I call a “flutter-foot”. This behavior consists of fairly widely varying the speed of the vehicle, so that I cannot use cruise-control anywhere near them. It seems to consist of some sort of relative ‘mindlessness’. It is rather common, among the ‘driving sins’ hereabouts.
Other than that, things are ‘just fine’.
May we all ‘drive with lightness’ eh? [That last syllable is a hat-tip to my Canadian cousins.]
