Ahhh but the power grids in these towns are down due to the fires in most places or been shutdown for safety ......
 Does your Tesla or EV take AAA ...AA .... Or 9V batteries    ?  sir / madam ..  :D

The servo might have one diesel tank, but have 3 petrol tanks... At times I'm glad my 80 is petrol for that sort of thing... the diesel 45 ute? Well, that runs on cooking oil at a push, and 20 litres of that would get me nearly 200kms.

Does the burnt down servo in your town pump diesel or petrol?

As an example - A Tesla 3 can put 250km range in under 15min.  Hardly a problem.

Also, most EV users will hook up when they get to where they’re staying, so people holidaying will likely have an almost full range vehicle.

How many people get somewhere running sub 1/4 of a tank and park up until they’re ready to go on the next run?

No power, no petrol pumps and no Tesla either......amazing how we rely on that dirty coal fired power.

Solar works . If we had an EV we could charge here off PV and Battery.

As I mentioned, you’ll find EV owners don’t run around on the bottom of their “tank” like ICE owners.  All those with EVs that I’ve met are far more diligent.

FYI- That Coal fired power is still more efficient / emissions are lower for the energy required to charge those EVs than the emissions from burning diesel/petrol to power a vehicle.

Interesting...New and hybrid electric cars use 4 times the amount of copper a norms generic unit from the 90s needs and has twice the carbon foot print in manufacturing...so many things left out.
Pretty sure we are in short supply of copper as well...great gimic...implications in change over could be 100s of years away realistically...

My 2 cents...

May not be a problem in most of Australia, at present.

https://www.disclose.tv/new-test-reveals-electric-cars-are-practically-unusable-in-winter-383233?fbclid=IwAR1zll9-ovNiCXqLO0Dgiv2q1dlKNAs7RptEu646LIiP7ADpQJFbqqo2sw8

"A new comparative test of the car picture shows that electric cars massively lose range in winter. In frosty temperatures, the range of four out of five test candidates dropped to under 70 kilometers, and that of the Renault Zoe to under 60 kilometers.

Due to its enormous battery, only the Tesla Model S was able to reach a range of over 200 kilometers even in winter temperatures, but the luxury car is in a price range (it is available from 78,000 euros) that most drivers simply cannot cope with."

I believe they will need to rethink climate control as well...it would decimate range in high temps...keeping the batteries cool would be the biggest problem on bitumen roads...instant inferno with Lipo examples.

All the issues raised re range, cold weather, climate control, copper shortage, etc are all just problems, with as yet unknown or uneconomical solutions.  But those solutions will come and probably quicker than most people think.

Tesla battery packs are liquid cooled to control battery temp and the vehicles also run a very effective AC.  Plenty of areas in the USA have the same temperatures as here and lots of Tesla getting around without a problem.

I know someone with a Tesla and happily does country runs in 40°c+ without issue and gets close to the advertised range with the cabin nice and cool.

A neat function is to pull up at a shop etc and put the vehicle in Pet mode.
A large sign appears on the screen saying the vehicle is climate controlled and pet is safe - vehicle then sits cooling the cabin.


We ran a comparison of our recent runs back and forth to Adelaide. We’ve done 19 trips in 3 months at over 900km return each.

Fuel cost is about $140 a trip x 19 = $2660.00 in Diesel
If we had used our friends Tesla it would have been $120.00 in electricity.  Each trip would require no more than 15 min at the Charger to easily make the return trip with a good 250km range to spare.


If the tech is this good now; imagine where it will be soon.

Best wishes to the wealthy...were the trips fully loaded...towing?
The other problem is having to change the batteries...2 years was a suggestion...5to 30k for a battery pack?

900 K's round trip...Model S has a max range of 600 K's, so a realistic 500K's.   So a full recharge needed at the 1/2 way point, and without a supercharger, approx 10hrs to charge with a normal power point from 1/2 charged ( which it won't be...more like 3/4 flat )

And the powers that be will soon find a way of charging you more for recharging an electric car than the normal household rate.

There’s 6 Supercharger sites on the common routes from here to Adelaide.

Putting enough charge to comfortably return takes about 15m (a coffee stop).

Nothing to do with wealth, Patrols weren’t cheap new either.

I’ll pose it to you thus... what’s your vehicle drink towing? Certainly more than when not.  It will all get sorted as the tech matures.

Not sure where you’re getting the battery info from - from Owners forums they’re getting 5 years+ and some serious mileages.  If you compare a new ICE vehicle doing average kilometres... (let’s assume workshop servicing)

$1000 for two full services a year
$3500 in fuel
That alone is $22,500 over 5 years.


Safe travels.

It is to do with weath...by the way for us tradies thats 22k each year...yes that how much It cost to run a sole traders car each year.

Anyways ...our Aussie average income is only around 44k a year... less that 20% of Aussies can afford to purchase a car that cost more than 15k let alone buy a home..replacing 30k worth of batteries every couple of years would hurt...those who can afford are not part of the majority in Australia.

It will start as a privelidge...but who will fund the rest? I should say public transport should be upgraded first...

Removing combustion engines from the commercial transport industry. Rail Truck and public transport sectors first.

One yhing is sure...Plenty to be considered.
