Where are you guys on the road?
I see maybe one other courteous, friendly driver per day (out of thousands) who is willing to spare an extra two or three seconds to do things like:
Let people merge onto the interstate (honestly, are other people trying to kill people who are trying to merge?)
Use turn signals (to indicate that they're going to turn..many people use turn signals but I haven't figured out what the hell for yet.)
Check their blind spots so as to avoid killing themselves and others. (is it that hard?)
Obey traffic lights
Let other people change lanes. I assume they're trying to change lanes for a reason so I'll slow down if someone ahead of me flips on their turn signal. I have never encountered any other human being willing to do this.
In many cases, even following the friggin' lines is too much for some people. Almost got run off the road by some old moron who couldn't understand a lane shift.
I'm not even mentioning what people do in parking lots. I'm amazed at the levels of stupidity of drivers in parking lots...
