Long distance at high speed is the worst case scenario for an EV, so it's a pretty useful figure to know, especially when cross-shopping cars. A fixed speed range test gives you a solid floor for range, with all other uses pretty much guaranteed to meet or exceed that number. The lone exception being cold weather performance, but the easy solution there is conduct the test at multiple temperatures. Most drivers in an ICE car can get pretty close to the EPA fuel economy in the real world, but in EVs there are some pretty wild swings. Some EVs outperform their EPA number and others can't achieve it, making the EPA number not especially helpful.
