The real question is how many EVs does it take to shift the oil supply / demand balance? And hence the price.
I genuinely that that we are about to hit the steep part of the EV adoption curve in the next 2-3 years, the historical rate of adoption is not a good predictor of future adoption.
Often most high mileage vehicles are new vehicles, the economics of EVs work out best in high mileage applications.
At the start of the war Russia assumed that Europeans would not be able to live without Russian gas, so far Europe has been able to do that fairly effectively.
China is an outlet for Russian oil but is adopting EVs rapidly as part of an official government policy. Currently around 24% of new car sales.
So far oil exporters are able to prop up the price by cutting supply, Russia has got more assistance from OPEC than I would like.
This (more EV sales) will not bring a speedy end to the war, but every little bit helps.
Sanctions are also disappointing to date and IMO an area the can be improved,
This war is definitely one that is an economic contest.
In the last 20 years the US has become the land of the SUV and pickup truck (ute). The Dodge Ram is the only full sized ute sold in Australia I believe. In the US the utes that size from Ford, GM, and Dodge are three of the top selling vehicles. There are a lot of options for each of the truck models that affect the outcome, but here are three standard equipment trucks compared to a Toyota Camry

They are incredibly common around here. I think we are the only people on our street who don't own a truck or SUV. I have the only electric car. There are a few hybrids, but no plug in hybrids.
I know someone who had a 2019 Ram pickup that got 7 mpg. It was so unreliable he sold it and got a GM truck.
When gas prices spiked there was someone on Nextdoor complaining that filling his truck cost $150. I chipped in and suggested he get an EV. Filling my car from and empty battery only costs $6.50 (electricity is really cheap here). A lot of people didn't want to hear it.
Cities may be big on EVs, but get out into the suburbs and ICE still rule the road. There are still a lot of people who are wedded to their ICE.
Beau cited Ukrainian defense intelligence for the predictions of Russia's longevity. You are free to disagree with them but I think they are already well informed about the various aspects of the Ukrainian military effort that you mention. I would also trust them much more than I would trust "the internet". This doesn't mean they are right.
Sure Russia will eventually run out of stuff but that is not going to happen soon. For example, Ukraine has only destroyed a few percent of the transport planes that have been recently camouflaged with tires.
I thought it was interesting that the Ukrainian defense predicts an economic collapse in Russia a year before a military collapse. I think this will come about from death by a dozen cuts more than by Russia running out of stuff because it all got destroyed by Ukrainian drones. Sanctions and lower oil prices and running out of foreign currency and getting ground down on the front and worsening logistics and sabotage and so on. Ukraine is lighting more fires than Russia can put out.
But I hope Russia will lose the will to fight (perhaps after giving Putin impromptu flying lessons) before their economy collapses.
Russia has a burn rate on their old Soviet gear in stock. When that runs out, they will have nothing left but new production which is there, but it's small. Perun recently looked at that issue.
Ukraine is probably coming to their conclusion based on the intel from satellite photography of Russia storage yards which are emptying out fast. I would expect Russia to run out of some things before others, so their loss of combat power if going to be patchy. Ukraine has been taking out artillery to speed up their burn rate. At the rate of losses, Russia will probably run out of artillery before they run out of tanks.
Russia does appear to already have some severe shortages of infantry weapons. We have seen many photos of troops in street shoes, and there was a recent complaint from someone on the frontline in a unit that was being essentially ground to dust in fruitless assaults who said they were throwing everyone into these infantry assaults, including the artillery crews armed with shovels. Several months ago there were pictures of Russians attacking in Bakhmut with sticks.
These are obviously not all Russian units. The VDV units appear to be fairly well equipped, but there are a lot of untrained cannon fodder units that have very paltry infantry weapons available.
As the losses mount, we will likely see more troops armed with ersatz weapons and fewer armed with real infantry weapons.
The army is slowly bleeding out, but they started with such a huge stockpile that it's taking a while to burn it all up.
