Rare earths are only necessary for permanent magnet type electric motors (lithium is limited too but not a rare earth) but most EVs use AC type motors that don't need permanent magnets: https://cleantechnica.com/2016/05/3...motor-ideal-choice-21st-century-electric-car/the environmental impact of electric cars is still suspect
they may save some in usage, but the manufactur of the batteries requires rare minerals, that create alot of issues

As for lithium, there are sufficient proven supplies and even though China produces (and consumes) the most, there are large sources in places like Chile and Argentina that aren't outright hostile to North America.
Sure you can postpone and ignore service intervals but I think Toyota saying to change a timing belt every 90k miles isn't excessive. If it fails you'll probably have to rebuild the whole engine. And MANY components wear out or die just cause, regardless of scheduled maintenance. Spend a few hours waiting in the service lobby at any car dealership...Yes all that 'factory recommended maintenance' is what the suckers do
For me I expect to pay nothing in maint for the first 5 yrs other than consumables tires/oil and that gets me to about 80k miles <$100 per year then I budget about $1000 a year after til I get rid of it somewhere around 200K miles. So always the EV proponents exaggerate costs of a FF vehicle I get it, its how you represent your business case.
Gas tax is a relatively small percentage of a price of gas - not enough to make it 3x as expensive per mile. The main reason EVs are cheaper to operate is because electricity is easier to come by than gas, and electric motors are way more efficient than gas engines, which drop most of their energy as heat. I think a lot more of it has to do with the enormous costs of extraction, transportation, refining, distribution, and so-on. And generally there's been no tax or cost associated (for individuals) with the price of the wars for oil or the air pollution associated with the gas (instead we just ignore it and we'll deal with it later). Fuel tax doesn't pay the entire cost of the roads and highways, and sure EVs should probably pay some equivalent and will eventually. You can also remove huge chunks of the entities like CARB (California), emissions testing for cars, and EPA's automotive divisions.On the flip I don't think batteries are an issue with an electric car other than it drives up the initial purchase price. Still too many pitfalls for me to own one here but certainly parts of North America its a suitable option. I actually want EV's to succeed because its gonna be better environmentally in the long term as they build support around the manufacture and operation.
Just have to figure out how to fix the roads cause that comes out of the gas tax around here, it's one of the reasons WHY gas is 3X the price of electricity. EV's aren't paying their share of infrastructure.
the world economy disagrees

"The likes of Tesla are choosing to use rare earth-based permanent magnet motors, rather than induction motors, in some vehicles, as they are lighter and more powerful. That is key to improving how far the vehicles can go without being recharged, according to David Merriman, an analyst at consultancy Roskill."
Lithium, cobalt, indium, gallium, and tellurium are not even rare earth elements. The rare earth elements are the lanthanides plus (customarily) yttrium and scandium.
The majority of wind turbines use induction generators. They do not require rare earth magnets.
Many EVs use permanent magnet motors incorporating rare earth elements but that is not actually required to make an efficient and high performance EV. Tesla uses rare-earth-free induction motors.
Most EVs use lithium ion batteries that are free of rare earth elements. Only the minority of EVs using NiMh batteries require rare earth elements in battery packs.
~95% of the PV market is based on crystalline silicon: no indium, gallium, or tellurium required.
Sadly, I have seen these same mistakes voiced by environmentalists who are genuinely concerned and not just trying to shill for the fossil status quo. These errors have acquired the folk-status of facts by sheer repetition.
Which is why I refuse to buy cars with timing belts, chain only. I'm over 50, don't worry well aware of what goes on in auto servicing.Sure you can postpone and ignore service intervals but I think Toyota saying to change a timing belt every 90k miles isn't excessive.

Maybe not where you live but fuel taxes cover it here in Canada
your cost per mile for the ev is low
national average is 12.4 cent/kwh
assume 35khw/100miles thats over 4 cents per mile (4.3)
in some states its up to 18 cents, some as low as 7
so that will vary with location
still cheaper than gas? sure, but not as much on average
throw in that in this day and age when electric companies want to put in smart meters to manage your appliances
edit: almost forgot. eventually you will have to add in a tax per mile. as ev do not currently pay a road tax. it is coming
i never mentioned global warming, and conceded the emissions.
i questioned the rare minerals usage and pollution
so whats the graphic for?
Saying something "may" be true isn't much of a concession when it is empirically true.
look at the entire statement. the question was on the overall environmental impact, not the emissions
but does that chart take into account the emissions from the electric generation?

but yes. everyone talks c02, no one talks total polution.
all forms.
Using that logic Hulu, Netflix, Amazon, etc. streaming video should not be successful because of all the people that lack high speed internet in the Midwest and deep south.
I believe once the real world range on electric cars exceeds 500+ miles along with faster charging times the tipping point will come and many of the range anxiety arguments will go the way of the horse and buggy.
i don't know. http://www.thetruthaboutcars.com/2017/02/lease-discounts-on-electric-focus/Your statement makes 0 sense, so I don't know why you'd say "using that logic". If Hulu, Netflix, et. al cost more than renting a couple of Blu-Rays, while continuing to not be useful for a large number of the population, then they very well might not be that successful at all. It's ironic because the thing that made streaming movie services successful was low prices (watching more than 2 movies in a month usually made up for your gas + rental bill, not to even mention the cable cutting possibilities that came later) and instantaneous access (Want to watch a movie? Launch the app, press play). Electric vehicles currently offer neither advantage over their gas counterpart. If they were substantially cheaper, and you had ultra-fast charging at a convenience that at least rivaled a gas pump, I assure you that electric vehicles would be much more popular than they already are, and our tipping point would have already arrived.
Plenty of range for commuting, shopping trips, errands. Probably many out of town trips for nearby stuff <35 miles away. Not good for an only car household but fine for a second car if the other is a gas car.
