Hey folks. I was the one that took that video. let me know if you have any questions.
Re:Tesla Roadster by opdahl on Friday November 17, 2017 @02:50AM (#15719990)
What is that sound that you can hear right when the car starts accelerating? Is it the tires slipping?
Re:Tesla Roadster by jandrese on Friday November 17, 2017 @10:11AM (#15722531)
Look at the road, he had already done that jaunt a few times before this video was shot. The road is full of skid marks from the wheels slipping before being caught by the traction control.

This car is absolutely traction limited. It should be able to post even better times with racing slicks.

What is the airspeed of an unladen swallow?
Re:Tesla Roadster by gargravarr on Friday November 17, 2017 @06:30AM (#15721103)
European or African?
Re:Tesla Roadster by nindalf on Friday November 17, 2017 @06:44AM (#15721201)
Is this relevant? Its not like the African swallow is migratory.

Not sure if you're trying to make a joke and it fell flat, or if you've never seen Monty Python and the Holy Grail and are missing the reference.
Re:Tesla Roadster by Beltiras on Monday November 20, 2017 @03:16AM (#15738543)
It fell flat. Sometimes to make comedy you have to attempt new things and sometimes they miss wildly. I actually started the thread so I do know the reference.
Re:Tesla Roadster by gargravarr on Tuesday November 21, 2017 @11:19AM (#15748911)
I'm not much of a Python fan so this is the first time I had the opportunity to make the reference. Annoying it fell flat!

Do you not understand what 0 mph is or why do you use scummy clickbait titles?

Re:Tesla Roadster by usaphp on Friday November 17, 2017 @04:45AM (#15720574)
Why did you sped up the video instead of posting the original? You can see it by the movement of people around the car at the moment of acceleration.
Re:Tesla Roadster by GijsjanB on Friday November 17, 2017 @06:35AM (#15721138)
Probably not sped up. What you're seeing is a sudden acceleration of the camera's viewpoint when panning to the left in order to keep up with the 1.9s to get to 60mph.
Re:Tesla Roadster by stevenjohns on Friday November 17, 2017 @06:04AM (#15720966)
Looks more like they jumped out of surprise rather than the movements being artificially sped up.
Re:Tesla Roadster by davidwhodge on Friday November 17, 2017 @11:18AM (#15723287)
I didn't speed up the video. That is the original.
Re:Tesla Roadster by ak39 on Friday November 17, 2017 @06:08AM (#15720985)
What can you see?
Re:Tesla Roadster by tgtweak on Friday November 17, 2017 @08:54AM (#15721937)
Would be good to get an answer on this from the author since he was so kind to show up.

@davidwhodge ?

Re:Tesla Roadster by shash7 on Friday November 17, 2017 @01:46AM (#15719640)
That's some unreal level of acceleration. Never seen anything like it.
Re:Tesla Roadster by lathiat on Friday November 17, 2017 @02:32AM (#15719890)
Something that really impressed me is how smoothly the Model S launches in the Wet, see here: https://youtu.be/iyXSJAICaBc?t=210 [Real Time @ 3m30s] https://www.youtube.com/watch?v=JNzLTW_l2q0 [Slow Motion]

Elon talked during some event how the latency / response time of the torque control in the Tesla drive-train is ridiculous compared to gasoline and for that reason even RWD models should handle well in the snow. To be fair, some people talk about the (at least older) RWD models being a bit crazy on Snow/Ice. I can only assume that the newer models are much better and the Roadster likely better again - plus it's actually AWD but anyway the point was more about the torque control :)

By comparison one of the kings of Launch Control is well known to be the Nissan GT-R. You can see in this wet launch that while it still does a great job, it definitely has some spin as it basically intentionally causes a loss of traction at the start, calculates the traction available based on the acceleration it does get to then adjust the power output and differential splits. https://www.youtube.com/watch?v=RTJGE0wzJpE

For other really fun scientific/computerised stability control, this video about the Koenigsegg Agera R is great: https://youtu.be/SywqgH7n-5g?t=34

It shows him literally reefing the wheel side to side at 1m15s while full throttle. Even my 2009 Evo X has surprisingly good stability management in the wet - and it is now probably nearly 2 decades old technology behind any of these other cars and only a 50k car not a 200k-1m car. Still crazy and computers are amazing.

Re:Tesla Roadster by alkonaut on Friday November 17, 2017 @02:44AM (#15719954)
I'd be pretty nervous running something RWD with massive torque and power on ice. I'm sure it's better to have a more predicateble delivery, but with ice 7 months per year I'm staying clear of high power RWD cars...
Re:Tesla Roadster by lathiat on Saturday November 18, 2017 @12:14AM (#15727859)
The electric advantage though is that you can infinitely (or well close enough) modulate that power delivery. And in fact I think they recently added a "slow and comfortable" acceleration option to the Model S (the opposite of Maximum Plaid :-)

The snow comments were also mostly in regards to the context of the Model 3 which is not that "high power" but it also has obviously quite a substantial amount of torque from a get-go compared to traditional gasoline torque curves.

Generally speaking though I would agree.. I love AWD, Breathe AWD.. and my Model 3 will be AWD :) .. and we don't get any snow!

Also 7 months of snow is probably very different to much less of it I imagine.

Wow, the shape change in the tires is crazy, didn't know that the effect is so big.

Kind of looks like it's from a game with bad physics. Except it's not.

Yeah ok, that's pretty rapid.
