There's a suspicious lack of real photos and video of this soon-to-be-ready vehicle that's set to ship to consumers in just 2½ years. Surely they're not still in the very early R&D phase, right?
The best actual photos I can find is of an oversized drone with a basic frame the size of a car, a "cockpit" in the middle that will barely fit 1 person, 8 propellers where the entire "car" would normally be in a car, and some light-weight foam side panels slapped on. No car engine or car wheels (except some small castors to roll it around).
Along with the (paraphrasing) "it's supposed to be a slow-moving vehicle while on the ground" comment in the article, I guess they're building a big drone with a small lawn mower motor to move you around on the ground.
