Area under the curve -- then that would be to establish average speeds, yes? I think the recorded road distances and travel times would be a simpler way to establish that.

Yes, that would have been a nice alternative to what actually happened. My pet gripe about Tesla in this affair was their advice to Broder to engage in stop-and-go driving as though that would help the car's range (it can't do that, it can only hurt compared to driving at a steady speed).

Area under the curve is distance. (Integral of speed over time is distance.) We know what the actual distances are so the actual distance could be compared to the area under the graph to verify its accuracy.
