"Torque is a static turning force. Yes the electric vehicle can create High torque but an electric motor is using maximum amps to create a torque at practically no speed. Not useful. "
Not useful? Wrong, wrong wrong. It is perfect for standing starts which all vehicles do all the time every time they start from rest. No clutch required to get off the mark, no torque converter generating heat and wasting energy, no weighty transmission with friction losses apart from a single reduction gear and a diff. The diff can be, and is on some models, eliminated with a motor on each driven wheel. Low speed and zero speed torque can be and is modulated by your right foot and is perfect for severe off-roading. Read up about the Rivian's off road performance.
"Also the high amp draw will ram the battery will expire very soon and not last long of that is imposed on it regularly."
Just like if you flog your ICE (Internal Combustion Engine) car off the mark regularly you get increased wear and tear. There are Teslas driving on their original batteries after 300,000
miles (480,000km). In normal use EV batteries are expected to outlast the life of the rest of the vehicle. The average EV vehicle warranty is 5yr/100000km (
mine is 5ys/unlimited km) and the average battery warranty (including
mine) is 8 years/160000km. What is/was your last ICE vehicle's drive train warranty?
"Sufficient torque at suitably geared road speed is better. "
That is exactly how they are made already.
Mine is 7.981:1. The engineers beat you to it, I'm afraid.
"Haven't seen many Tesla cars towing anything. Nearly every one I have seen has only 1 person in it, same for almost any electric car. "
Spurious argument. Pretty much the same applies for every car you see around town. Newer EVs now have a tow rating. Some cars becoming available in Australia are rated up to 1800kg and , the electric utes in the US up to 5 tonnes.
Electric desert travel?
Well, common sense says that's not going to happen for quite a while. But then as Hoyks suggested elsewhere, reduced fossil fuel used by EVs may make more available for longer for remote area travellers -if you will be able to afford it.
As for the Albanese quote,
well if you believe that that is actually what he meant then .... oh, never mind. Solar will charge a battery somewhere - a
home battery or a mega
grid battery or pumped hydro (which is, in effect, a battery) and then you charge your car off that - at night. Of course that won't be free, but it will not be fossil-fired and that was his point.
