And if one transposed the 'e' with an 'a' you'll be blowing raspberries..

OK, I noticed the same voltage rise and fall when I first bought my car. Read this thread and was happy for the info. However, now it's a constant 14+ and never drops. I've been on some half hour long joints down the Highway of Heroes expecting it to drop but it doesn't. So, does my car have a problem or must I go on a three hour cruise? (Remember what happened to the SS Minnow)

What kind of electrical load was there on this drive (headlights, AC, etc. turned on)? If the headlights are turned on, it will stay at a constant 14+ volts.

Headlights are set to Auto with the audio muted, (there is no off) during regular daytime running.

Your car doesn't have a problem, the problem is we live in Canada

Below a certain temperature (seems to be around 7-8C), the alternator will keep a constant 14.4V. I'm guessing to make sure the battery is at 100% as much as possible, to prepare for the next cold start.
It will also keep a constant 14V if your headlights or the rear defrost is on (and maybe other things I haven't noticed, like heating seats, etc).
