Yes and no, the materials to make EVs go are much harder to source. I think ICE engines are at this point nearly impossible to stop people from getting their hands on. I think I could source the parts to make a shitty ICE car/truck/thing but the batteries for an EV that has any chance could be hard. I think it does not really matter what the type of vehicle takes the market, it matters more that the current model loses viability as the consumer base can no longer afford or borrow for the modern car/truck/other.
If you can no longer get a 7 year loan for a 100k plastic monster, you have to get something else. Since there is almost nothing else new, you have to buy used (we are roughly here). Once the used market is hot enough that used cars are worth more then new ones (Think of a lada in hand being worth 2 on order) someone will disrupt that market just out of greed. Once you have another option for a cheap car/truck/thing you will see (or seen as this has happened) lobbyists push to have laws put in place to stop the upstart (CAFE, Chicken tax, motorcycle cc limits etc.). But now you don't have so much a reluctant market but an impossible one, people will literally be unable to support the old system. At this point something has to give, ether the government protections have to go, the old companies are forced to change, or the increasing the ability of the consumer to spend more (ether though subsidies or cheap loans). I think the overall economic situation means the cheap loans are out for now, subsides are rarely popular for luxury items (the current model has forced vehicles into this category), the governments are not so stable around the world making upholding unpopular laws less feasible, and lastly the old companies are at the end of the day going to pick profit even if it means change.
