To counter, each of gallon fuel produces around 20lb of CO2 when burnt, so take an average tank of 10 gallon x 20lb=200lb=91kg per tank. lets say you fill up once a week=52x91=4732kg of CO2/year
Now you have not provided the cost in CO2, methane, other pollutants, particulates from building rigs, fuel to run and bore, extract, carry, refine, then transport around the world to every petrol station.

Excellent, the Smart was about £2 for 100 miles, non Economy 7 and guesstimated using my crappy monitor thing. I want one more each day, no trips since I borrowed it have been beyond it's range, definitely my next car and I'd get it now if I wouldn't get shafted on depreciation on the current one.

Came out of the shadows right across the path. Car had no malice or intention to harm, far better than human drivers

I think "electric cars" and "autonomous cars" are getting unfairly banded together as they both need new tech and advanced control systems.
Autonomous cars seems really daft to me at the moment because if the driver (occupants probably a better term) is supposed to be there ready to take over if something goes wrong, but they havent had to have any input for a chunk of time leading up to that something going wrong, when they are needed theyre reaction times will be rubbish as theyre not concentrating on the road, and when they do take over, theyre ability to do something about it has been severely compromised.
In a normal driven car, you have to be concentrating to a fairly high level every second of every journey or your through a hedge. How can anyone be expected to see a problem, react to it, take control, take evasive maneuvers, not kill pedestrian etc etc from a cold start.
The only benefit i see from autonomous cars is the fact theyre currently being a good test bench for passive safety systems which can be included in normal driven cars to stop muppets (we'll never eradicate muppets unfortunately) from causing accidents.

It won't be the tech that will cause autonomous cars to flop, it with be the liability issues and insurance costs that ensue when a robot car kills a pedestrian.
The railways are a case in point: if 9 people died in a crash on our highly automated rail network then there'd be a 5-year public inquiry and a slew of safety recommendations.
Meanwhile nine people are killed by driver controlled vehicles on the roads every day and there's probably no more than 5 days of investigation on each of those deaths.
We seem to be able to tolerate human failure but we can't stand software or system failure.

That's right, I'm being rather generous with using 50mpg for ICE, more like 30-35mpg. Which would make 2000 miles cost ~£360 . Who would want to pay so much more for running costs when there is a perfect alternative for 99% of all your journeys + zero tailpipe emissions
