no iphone support? now who would want that?

Type in Bournemouth to Heathrow (three times a week) and see how many calories I'll burn - presumably before I die of heatstroke. Since there are no sensible trains (either by route or price) I guess it'll be the car then!

Helicopter, cause that'd be faster

Well, according to that screenshot, that car outputs 1150g/km of CO2. Is it a Humvee? I thought mine was bad at 240g/km!

is a gadget that shows the #calories used by the car, and the amount of C02 emitted by the pedestrian/cyclist.

How well does it calculate the pedestrian routes? The level of data for paths (sidewalks for the ignorant) is pretty poor.

Plus a calorie count for the journey, how does this work, I can understand it estimating it purely on distance and body mass, but what about the walking speed, walking style, amount of weight carried in the form of gym gear for your example of walking to the gym, etc, etc, etc. Not to mention the inclines of the route, which I have never seen in routing data, even the raw stuff.

Hmm. I'd prefer CO2 vs CO2 comparisons and calories vs calories comparisons.

That is: How many calories would I burn driving vs walking (because you burn a few calories just sitting around--though of course not that many).

Similarly: How much CO2 was produced making (and metabolizing!) the food I ate that gave me the calories to walk the distance instead?

Finally: The comparison being displayed in the screenshot seems odd. It appears that riding public transportation produces zero CO2 emissions? Witchcraft!

@Nick - "Well, according to that screenshot, that car outputs 1150g/km of CO2. Is it a Humvee? I thought mine was bad at 240g/km!"

Eh?

It is 7.7 lb (3,500 g) for 9.2 miles (14.8 km), which equates to 236 g/km - high but not unrealistically so.
