Probably an issue with the flux capacitorYup, actually as you get past 120mph the total time does start increasing again, but that's of little relevance.

Personally, I prefer a charging stop. That sounds boring to tears!I recommend using the Energy display to estimate range. Whenever you have a consumption near/over 270Wh/mi, look at the estimated immediate/last few miles estimate. If this estimate goes below your remaining journey, hypermile (when following a larger vehicle, you can see the average consumption going below 240Wh/mi). The sooner you start hypermiling the more of a difference it can make to your overall trip. For me, stopping for a few minute charging would be a greater nuisance than lowering speed and following some large vehicle. Hypermiling can also be used to reach a desired charging point for example near planned shopping or similar.
This works if you are tailgate close behind a truck. But so close you can’t see ahead so I think it is really dangerous. I guess if you are prepared to rely on TACC to stop you if the truck slams on the anchors you might be ok. But would you want to rely on TACC to stop you when needed given how often it does it when you don’t want it to?Personally, I prefer a charging stop. That sounds boring to tears!
Out of interest, how close do you have to be to the car in front to be able to notice the difference?

Slow down = more range. We "regularly" drive from Beds to Girona Spain. No problem with range matching bladder capacity
Mythbusters tested it - I can not remember the results other than it was pretty scary/dangerous at the distances they were talking about. They got it down to a couple of feet but it was a controlled environment.
[edit]random google - these may be the results Mythbusters: drafting 10 feet behind a big rig will improve mileage 39 percent
Drag grows with the cube of velocity.It might also depend on what car you are driving, but yeah effect is significant and as the drag grows with respect to square of velocity the assistance is more remarkable with velocity. If your range estimator says you will arrive at negative percentage, you can hypermile (various techniques) it to a significant plus value if you have enough range left.
For me driving slower than the traffic is rarely an option as it makes me hazardously sleepy.
No! Drag grows with the square of velocity. It’s power that grows with the cube of velocity.Drag grows with the cube of velocity.
The world cycling speed record is 183 MPH, achieved in the wake of a vehicle, so get enough of a tow in a vehicle with an inherently efficient powertrain and it’s anyone’s guess just how far you will be able to go.
Likewise, my ageing body needs a "Comfort Break" at about 2.5 hours, so will within the range of a M3.^ This is my logic. Unless I'm on a work commute from North England to South Wales, I will rarely go further than 150miles without a stop. If I did, I'd be getting cramp or my legs would start to ache, not to mention various biological functions needing to happen (eat/drink/wee).

I do a lot of short trips between 4 and 10 miles. I haven’t noticed the w/ml but it usually costs 8-20 miles of battery..Anyone notice/believe the horrendous Wh/mile numbers seen during the first few miles of any journey? Regardless of battery temp, air temp etc I almost always get 400Wh/mi showing for the first five miles or so, which then rapidly converges with a more nominal 250 Wh/mi or so.
I expected (and got) this in winter, but even after an 80 mile journey on a warm summer evening, if I interrupt it with, say, a 10 minute Supercharger visit I see these horrendous initial numbers after leaving the charger.
My experience also, but be happy: the short trips cost you 10X less per mile in fuel than a comparable ICE....I do a lot of short trips between 4 and 10 miles. I haven’t noticed the w/ml but it usually costs 8-20 miles of battery..
As it happens, did a 140 mile round trip today at 233 watts/mile and used 145 miles of battery.
The big take away from the Mythbusters attempt was how dangerous it is to tailgate / draft. @SpareHeadOne even had the battle scars to prove. More than just risk of collision going on.
Definitly happy. The charge power came from solar and cost nowtMy experience also, but be happy: the short trips cost you 10X less per mile in fuel than a comparable ICE....
A BMW M3 averages, according to various magazines, 26.3 mpg. So that is £6.75 per gallon or £0.28 per mile.
The Tesla M3 needs, based on domestic charging at £0.15/kwh, costs about £0.02 per mile.
Happy days... cost and range are interlinked with happiness!
