My only objection is the rubber-band low-profile tires on a giant wheel. I know this isn't even a full concept car at this point...but why on earth should a light-weight, low-cost robotaxi need big wheels and low profile tires?
As far as I can tell, low profile tires on big wheels has 3 potential advantages: (1) cosmetic/marketing preference, (2) allows for bigger brakes in a heavier or higher-performance car, and (3) might allow better cornering in a high-performance car. None of those should apply to a robotaxi...but the low profile tires will still bring their standard downsides: more expensive wheels, more expensive tires, shorter tread life for the tires, and increased susceptibilty to damage of the tire and wheel when hitting potholes and other road hazards.
I know it's just a pre-concept...but Step 1 with a robotaxi should have been smaller wheels and meaty tires to reduce up-front and maintenance cost and improve durability.
