I don't agree: It's not something that should be taken for granted. Battery safety issues may be resolved in a satisfactory manner but that's not a guarantee.

I don't agree: It's not something that should be taken for granted. Battery safety issues may be resolved in a satisfactory manner but that's not a guarantee. If the batteries can be made safer, then great. If it requires civil engineering and planning, then that's a bigger battle. There's also a matter of sunk cost and market forces: ICEs are fantastically complex machines, but also well-known. Most if not all of the edgecases have been worked out over the decades; and the cost to support the old infrastructure and supply chains are all known quantities. With EVs, manufacturers will need to build batteries or have redundant suppliers; which is also an unknown quantity and cost. You mention BYD, but given how China is dumping EVs and batteries below cost; the cost isn't exactly a useful metric. One hopes EVs take off for the sake of climate change, but there are real roadblocks that may stall uptake of EVs.
