I just clicked the temperature thingy in annoyance because I don't use Fahrenheit and to my delight, it just switched to Celcius

I did the same. I eyed it suspiciously and thought to myself, "This site is really well designed. Do you think if I..." and it did switch! The obvious interaction was implemented! Rare these days.

Mine was automatically set to Celsius ;)

Doesn't work on the the "meters" display, though!

Unfortunately that doesn't change the "mph" in the info boxes.
