Possible negative externalities aside...
Hmm..."possible" negatives...try breathing carbon monoxide. <grin>
Thats ridiculous. In the early days of the automobile there were several technologies vying for the market. There were electric and steam powered cars. The internal combustion engine running on an oil distillate emerged as the winner-because it was the best. The British Navy switched its fleet from coal to oil despite a domestic dearth of production for the same reasons.
Methinks things may have changed in the last 150 years or so.
Why the internal combustion engine won over it's competitors, which were at times faster, quieter? Seems marketing led the effort, and what followed was more development work for the internal combustion engine which provided a variety of benefits (less maintenance, higher reliability, and the like) in that arena. Consumers didn't say, "Hey, look at the thermal capacity of petrol! I pick that one!" It was a much more complex social and business phenomena.
The British Navy switched to coal for a variety of logistical and handling reasons, with energetic efficiency as an "oh, yeah, that too". If the argument is still "gas is the best because it's so darned efficient", then it falls short. The choice was not so much "Oh, yeah, oil!", it was "Gotta dump coal". At that time there were few alternatives - today there are more alternatives.
Gasoline is simply not "the best" any more, if it ever was. It is convenient. And it has an ever increasing social and environmental cost.
Who are you to decide what a consumer needs? It is up to them to decide what is in their economic interest. Consumers want speed, comfort, safety and range.
It is up to a society to determine what selfish interests cannot be tolerated. Consumerism without a balancing social conscience will eventually be Darwinned out, I would hope. Of course, plain old growing up will sometimes do the trick, too. Have you noticed? Consumers these days seem to actually want less dependence on oil. Kinda why SUV and Magnum V8 sales are in the dumps.
Why don't we have DDT? Why don't we have Thalidomide? Why don't we have lawn darts? They were all efficient and highly accessible.
The problem is not the energy source but energy storage. Batteries have have had a very low energy density compared to fossil fuels. This could now change with Lithium Ion and Lithium Iron battery technology. Hydrogen for the same reasons. It is the least dense element and requires crazy pressures to even be a consideration.
I see a crack in the wall...
On the contrary, that is the core issue.
The core issue is survival, public health. I remind you again: coal heating in Great Britain.
The reason it is entrenched is because it was "the best". It has been the best, because of its convenience. Fill 'er up. Less than 10 minutes later off you go for another 400 miles.
Another crack..."was". "Has been". Only now, it's "best" due to convenience. I thought we'd end up agreeing.
Convenience comes and goes, and is constantly changing. This too will pass.
Believe it or not, I am not "anti-car". I do like to see a thing called what it is, though - gas is convenient. It is convenient more because of marketing and profit motives, and because vested interests have indeed dismantled or sabotaged alternatives. Particularly today, alternatives are ever more viable and preferable.
