The (imo, more interesting) stats in the video are missing from the article text body:

   Total Distance:        728.7km,     452.8mi
   Total Energy:          77.5kWh
   Average Energy:        106Wh/km,    171Wh/mi
   Driving Time:          18:40 hours
   Average Driving Speed: 39.0km/h,    24.2mph
   Total Stops:           1 hour
   Total Time:            19:40 hours

I commented in another similar post but it seems to be lost...

My friend did 438 miles with his P85 by drafting behind a semi the entire trip. With the extra range (efficiency!) of the P85D I'm certain he could have hit 500, easy. I don't recall how many Wh/mile he was doing but it was crazy low.

I'm not sure why he hasn't been contacted about his drive, but Tesla does have the data and he's asked a couple engineers to look up his car and confirm. :-)

24mph is an excruciatingly slow average speed for a 450 mile journey. No wonder they were able to be so efficient.

obvious tip: this works for gas cars too. if you're extremely low on gas and in the middle of nowhere, draft a semi ... very carefully. luckily they don't brake very fast.

i did this more than a couple of times during college road trips when i was broke as a joke.

what the heck, 19 hours for what a 7-8 hour trip max? If it's not real world, then why give it a headline? A scooter can get 95 miles to a gallon of gas. To me that's amazing.

AFAIK lithium-ion batteries wear out quickly with deep discharges, so I wonder how much range he'll get on his next charge (or alternatively, how much capacity he lost.)

Is there something special he's done to get this much milage out of the car? It's only rated for about 300mi on a full charge, so I'm curious if it's just luck, or more?

When I first saw the headline on techcrunch I thought they modified the car somehow to get that range. That would have been a lot more interesting than just some guy cruising at 25mph.

The hypermiler thing always seemed kind of dangerous. https://en.wikipedia.org/wiki/Energy-efficient_driving

59 mpg in a plain old accord is impressive though.
