I'll chime in with my guess about those switches. Many accessories will require power. I saw in a video one of the prototypes had a connector in the slot where the double-din stereo would go.
So my guess is that those "accessory switches" are for turning the power on/off to the various fuses...
I have four criteria...
1) new vehicle,
2) can tow without voiding the warranty (only need 600# tow capacity),
3) 200+HP
4) RWD
When I'm ready to buy, I will get the least expensive vehicle that satisfies the four criteria above. As it stands right now, that will be the Slate even without...
