for a robotaxi you need large range so you don't have to charge frequently. for passengers from/to airports or train stations you need luggage volume. for commercial cargo you don't NEED windows, but does that mean you can't have them? for different sizes of families you need seats with seat belts and minimal storage, but if the seats are foldable and can slide on rails; then you could adjust how many seats, adjust for cargo, and move them where wanted/needed. I want to use mine for taking people to the grocery store and hauling back with even more groceries that the buyers have already paid for.Nothing that big will be practical for the next 5 years IMO. Battery pack sauce would need to be 200kwh or larger to get range larger ranges. Look at the eTransit 175 range. I would never buy a van with that kinda range of range when ICE versions are available. If towing you get half the rated range? Same thing goes for large SUVs. I don’t see the Suburban and Expedition get any BEV competition any time soon.
As far a robo taxis go. I don’t see any reason for a big van. Something Mazda 5 size. Maybe as large as a mini van?
The whole robo taxi concept will dictate size. Know that you don’t have to pay a driver to smaller taxis can make more money as it can run two different fairs at once and one larger taxi.
I might have 2 or 3 passengers but a lot of groceries to load, keep separated, and coolers for the cold items. Therefore I want sliding seats, folding seats with
seat belts, and doors on both sides and the rear. For long trips I'll want a lot of range...also because i want to charge via a solar system over 2 to 3 days.
