Looking at some videos, we can see that because of the slope of the back window, it won't be possible to store the shopping bags near the back of the cargo area.
They will have to be pushed toward the middle of the car.
I am then wondering of the practicality of this when doing shopping.
It might be good to have some kind of plate sliding out of the car, where you could put your bags and that you could retract back in the car. Like a drawer.
Sounds like it would make a great aftermarket accessory.
