Amazing, retreating to tires sizes to account for speed discrepancies? even if that was the case, he should run his numbers, 0.0708 in tire size diameter differences between the 19" and 21" wheel/tire setups does't make up a 6 MPH speed difference... It's actually .2 MPH @ 60 MPH....
I agree with dnanian that Tesla's response was overboard. They shouldn't accuse reporters of bad faith. I think they look whiny when they characterize driving around a parking lot looking for a charger as intentional malfeasance. The data with the comments are damning enough without trying to fabricate an agenda.
Broder's reply is an effective rebuttal to most of Tesla's complaints. However, he invents some seriously out there excuses to justify some of the numeric discrepancies. He argues that he set the cruise control at 60 mph, but the car went over 80 mph because "Most drivers are aware that cars can speed up, even sometimes when cruise control is engaged, on downhill stretches." (This is I-95 in Connecticut, not a drive down Mt. Washington). or that the difference between his article that said 45 mph and Tesla's log that says 60 mph "may be the result of the car being delivered with 19-inch wheels and all-season tires, not the specified 21-inch wheels and summer tires." The 245/35R21 tires are less than 0.2% bigger than the 245/45R19 tires, so how can that explain a 30% difference in speed?
I know it's bad for a reporter to say "I must have misreported the speed by a few mph", but the data clearly demonstrates he misreported his cruise control set speed. Trying to pass it off as anything but a bad memory or bad note-taking seems to just further damage his credibility to me. Broder should have simply not responded to this.
To Tesla I say: don't assume bad faith, even if bad faith seems readily apparent to you. Just report the facts, and let readers form their own conclusions.
To Broder I say: don't fudge the numbers by 10%. You're a reporter; get the data correct. If you had said you set the cruise control at 60 mph instead of at 45 mph, and that you charged for 47 minutes instead of 58 minutes, Tesla wouldn't have many charges that could stick, and you'd still have a story. (Namely that you can't drive a supercar like a supercar if you want to get 200 miles out of it, Tesla's reported range numbers can be deceivingly optimistic, and the car loses a ridiculous amount of rated range overnight.) There was no reason to fudge the numbers.
