Are Electric Cars the biggest con on the planet?
Discussion
No, they're not a con. There are technical/economic challenges to overcome (range, charge speed, cost, weight to a lesser extent, charging provision)- these largely will be addressed in time because that's what engineers do. The profit incentive is there, which means technological innovation will happen.
We're not at a bad point at all considering they've only been under serious development for a decade or so, and even then only by certain manufacturers.

Biggest observation now is the awareness and bring these issues to the table, that’s a good thing. child mining etc. guys that stuff was happening anyway! Yet everyone pretends to be woke when the way we have been taking sulphur out of fuel for years has been ignored, we now have a bigger desire to know where stuff comes from and the sustainability of the full systems.
Problem is you have to try to look at both sides of the coin before deciding it’s already heads. Which is fundamentally what most people are doing.

Yep. BMW have managed to make electric motors in the iX models WITHOUT rare earth metals. They claim it also has the benefit of improving how the motors perform too.
There was a review of the 50 model on youtube where he tested 0-60 even with battery down to 8% and was still getting 0-60 around 4 seconds.
BMW are using a brushed design, which in isolation sounds archaic, but in practice greatly improves the ability to control the energisation of the rotating field. The actual design of the brush arrangement looks to have a very low wear rate, and may even last the life of the motor. If not, the brushes (or carbon shoes more accurately) are easily accessible at the non-drive end of the motor.There was a review of the 50 model on youtube where he tested 0-60 even with battery down to 8% and was still getting 0-60 around 4 seconds.
This mean you can alter the field strength to deal with various speed and load conditions, as well as fully de-energise the motor, even whilst it is rotating. This can be useful for fault scenarios, as well as allow allowing one axle to be de-activated on demand, for example to reduce unnecessary energy consumption during cruise.

disagree. if crazy elon hadn't catapulted EVs into the mainstream, nobody would give a toss where and how the cobalt mined to process their fossil fuel came from. it's used as a stick to beat the EV market advances with, but it's got sProblem is you have to try to look at both sides of the coin before deciding it’s already heads.

Personally, I don’t think you should be on Pistonheads unless you’ve owned a TVR. Extra points for an electric one. 
Somewhat on topic, TVR is going electric from 2024
Mind you, a Sagaris with Tesla battery/motor would be high on my list.

It's BMW, I don't believe this for a second!I've known motors where brush failure causes local overheating and it's all downhill from there.
Better to change the brushes at X,000 hrs maybe?

The benefit of permanent magnet (ie using rare earths) is cost, and efficiency.

All these naysayers! If this was 1900 on 'Equineheads', imagine the uproar if loads of the flat-earth public refused to accept noisy, smelly, expensive and unreliable horseless carriages. Relax, the whole EV thing will work out fine over the next couple of decades.
we have a winner! people still keep and ride horses. expensive gig though.page3 said:

For an impractical and silly weekend car i want the noise, the smells, the vibrations and the chellnge of driving it.

Having had a fantastic Eco day out , paddle boarding on the River Bur, Norfolk.
I return to my thread ,to find that 'Free Speech" is not encouraged, my original post being Not Obeying PH Rules !!!!!!
As the OP, I still think EV cars are a con, and there existence does not help the planet anymore than killing cows would to stop methane, there I've said it again.

you're correct in that EVs alone won't solve a great deal. they have to proliferate in connection with renewables/ nuclear/ whatever power generation doesn't involve burning stuff.I return to my thread ,to find that 'Free Speech" is not encouraged, my original post being Not Obeying PH Rules !!!!!!

i think they are miles better to drive day to day. anyone who has actually driven one for a bit will agree.
