Begin with the fact that answering "undecided" or "TBD" is perfectly suitable for an answer right now and they may consider some questions as feedback in a particular direction if needed.
Will there be underbody aero-panels? On the left of the steering wheel, is there a slot for a speaker...
That tailgate picture is of the Canoo pickup tailgate. There are videos of it in action (cgi action though) where the tailgate opens in two then the extender slides out and there is a fold-up section which completes the end. The whole assembly adds 2 feet to the bed length. I have no idea how...
I'm not sure about the fastback, but I think they intend the SUV kit to be a flatpack and should stack easily on the side. I saw in a video from the launch that the sides and top were separable panels.
To preface this, I think Slate should focus on and release the Blank Slate before considering another model. That said, eventually they will very likely have to make and release another model, and I would like this thread to speculate into that possibility.
My guess would be a 2-door long bed...
At the launch event they wrapped one in about an hour, and from one video I saw it only took 2 people to do it. So I figure about 2 man-hours to wrap, maybe 3 for someone not used to it.
I once owned a Chevy Malibu that had both disc and drum (disc in front and drum in back) but primarily used the disc brakes to stop. The drum were only used if really needed. Brakes are needed to keep the vehicle stationary when parked.
The one thing I would like a solar panel for in an EV would be to power the Battery temperature management system to optimize battery health and longevity in sunny hot areas.
That's mainly just an example of gripes I have with it. Why should I have to swipe screen to my right, when I can easily just swipe the vent in front of me? It's just another part that can fail and extra cost and complexity that isn't needed.
From one of the interviews, it sounded like the numbers weren't final yet. When I compare it to other similar EVs that have similar motors and batteries, the numbers Slate gives are underestimated. This could be due to terrible aerodynamics or they just want to underpromise. Vinfast got into...
That one screen to rule them all is the biggest reason I never want a Tesla. I want the speedometer to be in front of me. Also, I don't want to have to go through menus to adjust things like the vents, why do those need motors anyway?
