This dashboard device tells you your average speed, updated every x minutes. You can determine how the duration of your rest stops or meals affects your average speed. For some reason, I always want this information on a long trip.

You'd need a reset button, to indicate when the trip starts.

DrBob: But of course.

po: The device should be disabled in heavy traffic, as it would only fuel motorists' rage...

Baked. I had a Beemer, once (never again), that had an onboard computer which would display just about every piece of irrelevant information you could desire.

Baked without a Beemer; my old '88 Carlton (Opel Omega, Holden Commodore) also had an on-board computer which showed average speed, instantaneous fuel consumption, range, and a host of other stuff. At least, it would have done, had it been working.

What about a personal version? I usually budget 90 minutes of travel to & from work, on public transport, a distance of 26 km in two segments. It will have to exclude time spent waiting for the bus.

My car (VW Passat) does this, but it's useless.

My dad has a Passat too. The fuel consumption part interests me.
I'd like the personal version. It strikes me that you could easily bake it, though, with a notepad to mark the times (the time you got out of your front door, stopped at the bus stop, got on the bus and arrived at work) and a map to measure the distances (only need to do this once, if you take the same route to work each day) and a calculation of the speeds on each segment. Or you could just measure the distance to work and note how long it takes to get there. How about a halfbakery users' comparison of distance, time and total cost of commuting per day?
And add it in to the Job Morality Indicator - no point in working for Greenpeace if you don't use public transport!
