Regen "doing my braking for me" does not literally mean "something else is in control of the braking". It means, "regen is applying the stopping force, instead of friction brakes". At least, that's how I took his statement to mean since that's how it works.

@Whoopsy have you driven a Tesla for any length of time beyond a test drive - it's really quite easy to "coast" in a Tesla I do it all the time and it's not like riding the brakes all the time - but maybe your experience is different.
At other times I also don't need a test drive to buy a car, .i.e all the Porsches and whatnots.

In engineering perspective one pedal driving is the most normal and natural way to control output. Push to increase output and pull to decrease it. Every engineering product is designed this way. We had been doing it the hard way simply because there were no good solutions with ICE.
Let's see, bicycle, airplane, train, are a few 'engineering products' that are not designed that way.

I spent about 5 minutes looking for it, and can't find it now, I will keep trying. It was an investor report which wrote this <5% eye on target reached. However, other articles report similar numbers of monthly etron sales of only about 200 cars https://www.businessinsider.com/tesl...-e-tron-2019-8
As an update, they sold around 1800 etrons just in the US in Q4, 5,000 year to date.

I don't know the international numbers.

I took a test drive in a Turbo today. Great car. Here is my trip data. The drive was on suburban streets and at least 60% highway driving at speeds up to 90, but generally around 70. Most in normal mode and auto regen, but the salesman was moving around modes and regen settings. We did no do any launches during the drive.
by my calculation, about 239 miles on full charge. We are considering a 4S, so I would expect a bit higher with the lower powered car.

You can't turn it all the way off. Just to low. Which is a substantial reduction, but definitely not the same as coasting.
When I was learning how to move my foot to "coast" as noted in my post above, I couldn't believe how far the car would keep going and not slow when the power bar was in the "coast" zone. I thought, "this car might show that I'm neither applying power nor regenning, but I'm still rolling really freely, this can't be right". Then I learned how to put it in Neutral, and tried a few tests coasting in Neutral. It's ridiculous. It's like a freaking fidget spinner. The car just keeps rolling!

What you feel is the weight of the car. It has a large momentum due to the weight. Rolling resistance isn't very different from other cars, it however has slightly better aerodynamics.

And here is the curve for Taycan vs Model S. 100% efficiency, all accessories off, constant speed:
Taycan Turbo equals Model S Perf on 21" wheels. If I'm not mistaken Taycan has wider tires. And I guess 20" rims, but haven't seen that data yet.

Physics don't lie. And I had similar experience.
You are correct about the Cayenne. This is the 2019 Cayenne / Cayenne S. It needs about 70% more hp to keep the speed constant.

The kinetic energy is E=1/2 m v^2 https://en.wikipedia.org/wiki/Kinetic_energy
The kinetic energy of the Model 3 is 4072 / 3186 -1 = 28% more compared to the BMW 330i. That's how much more energy keeps pushing the car forward while having similar rolling resistance.
The additional 800lbs for the Cayenne gives 20% kinetic energy advantage but it needs 70% more hp to keep the speed constant.
