When the vehicle is autonomously parking itself is where this really comes into play.
Yes, but unlike a gasoline powered car the typical "penalty" for forgetting to "refill" it is higher.
If you forget to plug the car in on the wrong day, you might be stuck for upwards of 30 min waiting for it to charge. That's compounded with the fact that there are comparatively few charging stations available outside of home.
Contrast this with a car where if I forget to fill it up the night before I lose 5-10 min and can find a gas station at least every few miles.
The forgetting problem can be solved with an app: "Hey! I notice you've been parked at home for 10 minutes and aren't plugged in..."
Luxury cars have a lot of features that exist purely for convenience, like this one.
2 things:
1. Sometimes I'm in a hurry and I think I will plug it in later... and I don't. And that turns out to be a bummer. :)
2. If this thing parks itself, it has to plug itself in, or there is little point to the self parking.
I love my tesla. It's incredible. Best car I've ever owned. I've owned... 20 cars? But it has to be charged daily or it's a liability.
