Few pictures for the P3 fans out there.
I was going to say that this didn't happen... But then you had pictures !
Congrats on getting such an early chance at an extended test drive. And thanks for posting about it.

Regen does not reduce braking distance. The braking distance is limited by the traction of the tires.
I am curious whether the AWD will indeed have stronger regen though. Has that been answered?

Super pics thanks for these and informative report from your test driveFew pictures for the P3 fans out there.

In that sense regen will reduce braking distance. The problem is regen is only .15g acceleration and the brakes are about 1g so you’re not getting much. It would be interesting to have a car with true one pedal driving (no brake pedal). It be sort of like having a dead man’s switch. Remove foot from pedal = full brake pressure.I haven’t seen any studies on this but it strikes me that regen almost certainly reduces real world braking distance in many cases.
Reaction time can be a significant portion of braking distance and part of that is the time to physically move the foot from the accelerator to the brake and for the brake system to engage.
One resource I found estimated the time to physically move the foot from the accelerator to the brake as 1/4-3/4 second. STOPPING DISTANCE (Safe Drive Training)
At 70 mph you are traveling at 102 feet per second. Using the 1/4-3/4 second estimate this means 25-75 feet of braking distance is just the physical reaction time to move the foot to the brake.
Regen kicks in faster and begins slowing the car down before you hit the brake. I have felt this happening in everyday driving with both my Model S and 3. Stronger regen should have a stronger effect.
Would be interesting to see someone take a deeper dive into this.
It would be interesting but I wouldn't want to drive that on a daily basis.In that sense regen will reduce braking distance.

Who takes 3/4 of second to physically move their foot from the accelerator to the brake in a panic stop?
People who aren't paying attention, and really old people.Who takes 3/4 of second to physically move their foot from the accelerator to the brake in a panic stop?
He was talking about the time between when you start lifting your foot off of the accelerator and when you press the brake pedal. That's the only time that regen is helping reduce stopping distance. I can understand how reaction time could be that long.People who aren't paying attention, and really old people.

I hate to sidetrack this wonderful thread any more but any chance you can point me to a source on the .15g? My Google-fu came up empty on a quick search.
No, but dual motors mean increased regen braking & will ride tire traction limit. You won’t notice sport brakes unless you’re on a racetrack & have the sticky 20” tires.

From motortrend. Not sure what Elon is trying to say in that tweet but 1g of regen at 60mph would probably cause the battery to burst into flames. Also the motors aren’t large enough.
Tires = slang for slicks, and yes trap speedOn what kind of tires? haha. The Model 3P will feel slow compared to that. Does your Civic have an interior?
EDIT: I'm assuming you mean a 135mph trap speed

from experience, if you just drove it off the lot just a few days ago, knock off 20% or more. If itit less new? Better move on.Awesome that you got to take a unicorn home for the night, @Limited! Thanks for the write-up and the pics.
On a completely unrelated note, has anyone gotten a trade-in quote from Tesla on a 3LR? Asking for a friend.

I bet you mean anyone over 30, right?and really old people.
