Sweden also has numerous tax breaks for buying electric vehicles, and does not properly tax the externalities of producing electric cars (running/refueling EVs, however, has very minimal negative externalities)

True, haven't looked at the data in some time but the breakeven point in regards to LCA comes fairly early though when comparing against ICE cars.

It depends greatly on the ICE car and driving assumptions. For someone who generally only makes short trips, a plugin hybrid is going to be a more environmentally friendly choice long term, given the significant amount of emissions needed to create the batteries for large range BEVs.
