Nah, if Google maps says it takes 10 hours, then it takes 10 hours with stops unless you're in the bottom 10% of traffic (such as if you're a truck towing a trailer).
If you're like most people going 5 to 10 mph over, then you'll beat Google maps time by about 15 minutes per 2 hours of drive time without stopping.
That doesn't make it a bullshit test. It makes it a different test. IMO range is more important than efficiency.
And if DCFC stations were everywhere, then I'd agree that would be more of a factor. But given that a 15 mile difference in range can be the difference between 100 miles between stops and 200 miles between stops, I'd still say range is more important than charge speed.
Doubly so since the highest range EVs are also among the highest charging speed EVs.
