Besides the obvious cold temperature that affect the batteries, it seems that everything else (incline, tires, air resistance, road conditions, etc) affect EVs disproportionately? Never heard of an ICEV loosing 50% range on a full tank because of bad conditions?

Both EV and ICE cars waste about the same amount of energy on common things like air resistance and tire rolling friction.
However, internal combustion engine also loses majority of its input energy as heat waste. That’s why ICE cars have huge radiators up front. All that burned fuel generates a lot of heat, but that heat is not helping move the car.
EV motors don’t generate that much heat, and most of the energy goes into moving the car.
If you chart the energy losses as a pie chart, in an ICE the engine the waste heat takes most of the pie, so other factors seem insignificant in comparison.
In an the EV the heat waste part of the pie chart is small, so other factors are relatively more significant.
