EVs are still cleaner even when powered with coal by the way
One argument that has been made against electric vehicles is that we must decarbonise the power system first otherwise cars are no cleaner than if they use gasoline. But a new study suggests that EVs help to tackle climate change in all but the most coal-reliant countries - 95% of markets globally.

Part of it is that power plants run at peak efficiency, while car engines do not (often they are idle, or operate far from their peak torque). The best internal combustion engines, in Formula 1, are about 40% efficient, normal engines are way worse.
And regenerative braking is a big factor too. When I turn it off in my EV to clean the brakes, energy consumption is around 20% worse.
That being said, I agree transitioning too fast will be too costly for Indonesia. But imposing a heavy pollution and weight tax on large SUVs - and cleaning up the power generation - definitely can. Also incentivizing mild hybrids - you don't need a large battery to take advantage of regenerative braking.
Going too fast will backfire, look at the Gillet Jaunes in France.
As for mining ... if Indonesia doesn't use it, batteries will still be produced either in country or with Indonesian sourced nickel anyway.
