Out of curiosity, what's the point of a driver in something like this besides to have a human in the vehicle adding weight? Are they doing much?

Serious & maybe very ignorant question.

- Edit - For clarification, my reason for asking was due to this occurring in less than 1 second. I don't understand what the driver does as I'm assuming they have no gears to shift or turns to make.

Very cool, but also kind of impressive that a Tesla manages this in ~2.5 seconds while doing all the other stuff a production car does. What time would a Tesla get if you stripped out all the extra weight?

I'm pretty sure a Tesla spends most of its 2.5 seconds traction limited. Ie. if you could fit gearwheels and drive on a toothed road, I think a stock tesla could accelerate faster.

Could we maybe change the title here and change it to 100mph? I realize this is the original article title but EV + 0 to 100 led me to believe the article was talking about battery charging speed.

0 to 100% fully charged in less than one second?

That sounds a lot more dangerous than 0 to 100km/h.

Nah, this thing is electrical. And in order to get that kind of power you're going to need plutonium.

That's almost 3Gs of acceleration. Impressive!

Thanks! I was about to ask how many Gs this translates too, my physics are a bit rusty...

In GNU units you can just do:

  $ units -t '100 kph / (.956s) / gravity'
  2.9629132

On a related note in the sports car community its been interesting to watch Acceleration stop being a mark of a performance car. There is even a lot of chatter around this being the end of the supercar segment since there are family wagons that can now do 2 second 0-60 runs. On top of that the speed is now too much for anyone to reasonably use off a drag strip or circuit.

Now there is a huge emphasis on engagement, dynamics, and a bunch of vague "feelsomeness" as sports cars slowly become like horses.

The march of time is interesting...

>What time would a Tesla get if you striped out all the extra weight? (seats, glass, electronics, roof, etc. etc.) That's been done - you don't actually want to remove things like glass because the aerodynamic efficiency loss doesn't outweigh the weight removal. https://www.youtube.com/watch?v=ywvGbus3yxo

Neat! It looks like their 0-60 mph time was 1.37s.

Raises the stakes, provides a degree of accountability.

Otherwise it’s just a missle with a required degree of ground contact, no?

I assume it's because racing, as a sport, is a lot less interesting without the variable of a human with particular skills operating the vehicle. I doubt crowds would be as interested in watching cars race on autopilot, though it'd still be kind of cool, I guess.
