Hi all - recently I've been getting a notification from the Tesla app that the charging cable is not secured/loose when plugging in to public charges using the J1772 adapter. As a result it does not charge at all though the charging stations still say they're providing power. Supercharging is...

In my experience, if you're driving as you describe then you can probably get by with charging once a week (so 6-7 days without a charge).

Totally agree with you. Have found that showing percentages instead of mileage makes a difference psychologically. Otherwise speed really is not your friend on longer trips

I love Ithaca - enjoy. Hope you got some time in Taughannock, so beautiful up there this time of year. And great efficiency! I drive fast, am impatient and don't like to be told where to go (i.e., driving up Route 17 from NYC to Ithaca would be unwise in a Tesla, but is a magnificent drive)...

Right - the 150 miles jives with my original quote of 40-50% of estimated mileage: 326*.45= ~150mi. At 80mph, you're stopping every ~2 hours for 20+ mins to recharge (provided you've stayed on the route you're given). Like I said, amazing piece of technology, but less flexibility and more...

Sure. That article is good. I think the intuition for 1/v is as follows: if you increase speed 3x, you need to "move through" 3^2 = 9x drag at a speed that's 3x faster than your original speed, or in 1/3rd of the original time it would have taken you. So it would not be enough to simply overcome...

Interesting - counterintuitive given the physics. Thanks for sharing. That said, these are pretty narrow bands - 55mph to 75mph - suspect you'd see a more meaningful decrease at higher speeds. Anecdotally, I am definitely not losing range linearly above 80mph. Once I have some more data...

I'm departing my lane on this one, so to speak, but as I understand it: - At incremental velocity v, you hit v times as many particles at v times the speed - hence v^2 incremental drag - To overcome v^2 incremental drag, you must do v^2 work in 1/v the amount of time for any set distance since...

I've only used the former two, but have found that if you obey the speed limit, the in-car nav is pretty reliable. It's also the closest to your battery and can make real-time adjustments for weather, driving, etc. I think the route planner on Tesla's website is a sales tool and overly optimistic.

Well said, but I think you need a cube of extra power, not square. The square is incremental drag, so you'd need 1.3^3 (2.2)x power to overcome 1.3^2 (1.7)x drag, resulting in 69% more battery for 30% increase. I think this then scales as a square: Speed Increase Incr. Drag Incr. Power...

FYI loads of car carriers with MYs and M3s down the I-5 last night...

Totally. The EPA range is nonsense, much like the estimated delivery date. Sweet spot seems to be 70-75 - I start losing a lot of range when I'm in the 80s. Thanks everyone for all the feedback. I posted a separate thread with my findings from this first road trip here...

Having just completed my first long trip in the MYLR (~900 miles roundtrip from LA <--> Bay Area), here are my findings and notes going forward - probably obvious to most but maybe helpful to fellow new Tesla owners shocked by real world range and prospective buyers: Estimated range is BS...

"parachute" 😂 😂 well said! The formula makes a lot of sense and is essentially what I experienced coming up the PCH at 70-80mph - about 0.4x real vs. estimated range. Really great way of thinking about it. Thanks for the mini primer. Assuming 50mph base (per above), I was traveling at 80mph...

Great videos! Glanced through the stats - looks like you were averaging 300-350 Wh/mi at average speeds of around 75mph for the most part. Is that fair? Did you find yourself stopping every 2 hours or so, and did the range estimate ever differ significantly from what you achieved despite keeping...
