I do it in a 15-year old non-EV no trouble at all, no need to waste time stopping en route.Hopefully ... by the time you need to do that in a 9 yo EV there will be adequate en route charging provision.

Quite so. But we are years away, decades probably, from having sufficient clean power to produce that hydrogen.So we need solutions which work, not band-wagons. It isn't relevant that hydrogen is only 30% efficient (or whatever) if it releases no carbon in the overall cycle and provides the necessary range.
There is talk of mixing hydrogen into the gas supply grid to 'decarbonise' it, but as with bio fuels there are limits to how much can be done before you have to start modifying the transportation and consuming equipment to handle it.Suppose you could somehow "hydrogen enrich" existing transport fuels and retain compatibility with existing engines - that would provide a stop-gap.
[Devil's Advocate = ON] Are you sure there are sufficient resources to make and replace the batteries required? And what to do with the exhausted ones - can they be recycled indefinitely? It seems to me EV has not just "electricity" on its consumables list. Are we heading for a future where there is a de-democratisation of personal transport and it will only be available to the few highest bidders (Tesla - I mean you!)?at present you'll need about 2.5 times more generation capacity for hydrogen than battery.
Only naysayers have said there aren't sufficient resources - usually lithium and cobalt get the mention. Cobalt currently has ethical issues in the way it's mined, but isn't that rare. Lithium is abundant.Are you sure there are sufficient resources to make and replace the batteries required? And what to do with the exhausted ones - can they be recycled indefinitely?
Definitely true. It takes a lot more energy to build an EV with a big battery and there is a fairly high mileage needs to be covered (obviously varies with the cars) before there is a break even between the energy/CO2 used in construction and that used in propulsion.It seems to me EV has not just "electricity" on its consumables list.
Opinion is that self-driving cars will be the big thing that changes personal transport. Possibly more democratic?Are we heading for a future where there is a de-democratisation of personal transport and it will only be available to the few highest bidders
In what way? Will they not be even more expensive to make and maintain?Opinion is that self-driving cars will be the big thing that changes personal transport. Possibly more democratic?
Why? Most new higher spec cars already have significant self-driving capabilities. It's mainly a case of a bit more computing power and 'better' software. The extra cost from now is trivial.Will they not be even more expensive to make and maintain?
Not really. Far more sensors are needed, and vastly more computing power complete with redundancy. I am also concerned about systems which use active rather than passive (receive only) sensors (including data networks) - it's all very well when there are relatively few such vehicles on the roads, but what happens when there is (say) a radar on every vehicle, where the possibility of interfering with each other multiplies exponentially?It's mainly a case of a bit more computing power and 'better' software.

I never bet, but...Once you remove the need for a driver the cost of a taxi over car ownership becomes very different.
I am not a betting man, but...Hopefully ... by the time you need to do that in a 9 yo EV there will be adequate en route charging provision.
Not really. Front and rear cameras are already common. Most phones seem to have 3 or 4 these days. GPS is almost standard.Far more sensors are needed, and vastly more computing power complete with redundancy.
There are a lot of cars around now with forward radar for emergency braking and/or smart cruise control. I've never heard of interference being a problem (I imagine they all use coded signals).I am also concerned about systems which use active rather than passive (receive only) sensors (including data networks) - it's all very well when there are relatively few such vehicles on the roads, but what happens when there is (say) a radar on every vehicle, where the possibility of interfering with each other multiplies exponentially?
Obviously any tradesmen will need their own transport which is basically what you are doing. But you are not most people I suspect. Aside from a few shopping bags the only stuff in our cars (and there is quite a lot) is what's needed at times to run the car - ice scrapers, cash for parking, spare spectacles.My car is a mobile cupboard - it has things in it I don't need in the house, but will be needed out and about or at destinations. The thought of having to drag all that in and out of the house every time completely changes the outlook.
Oh yes, that pesky time problem. Those extra few minutes a week that everyone has to destroy the environment in order to save.You would also have to allow much more time for journeys. One fundamental aspect of car ownership is instant availability. Having to hail on-demand transport would be subject to random delays
I doubt it will happen in mine, though I'd like it to. Once I have to stop driving I'd rather not be entirely dependent on buses and taxi drivers.I just hope it won't happen in my active lifetime.
Wow. I hope the car battery manufacturers read that article. Shocking stuff.
Not that many! I think you must circulate in afluent circles.There are a lot of cars around now with forward radar for emergency braking and/or smart cruise control.
Err, no. According to your projections, demand will exceed supply. Provision will not be made for peak demand.The only extra for a self driving taxi is the time for it to arrive. Initially that could be quite variable but once they are plentiful then it's likely to be quite short, certainly no worse than current taxis/ubers.
Aren't I? Who says you are? Everyone looks at things from their own perspective, I'm simply trying to widen your view of what might be "normal".But you are not most people I suspect.
