Not sure I agree...
It's simply more ammunition for ICE advocates to argue that EVs are not up to the task, ignoring the fact that ICE vehicles likewise go roughly 25% less far on a tank of gas, when traveling at 70 mph rather than 55 mph.
While a range chart, at various speeds and conditions, is useful information, I think that standardized range tests should be based on as few variables as possible (i.e. no wind, flat terrain, only the driver with no passengers or cargo, 55 mph average speed, 70F temp with no precip, etc). Controlling as many variables as possible, when conducting such tests, is the only fair means of comparison.
As far as winter driving is concerned, EV advocates need to point out the fact that ICE vehicles fair better in cold weather because internal combustion engines are better heaters that they are a means of generating useful work. An ICE is grossly inefficient, which often seems to be overlooked...
