The urban design absolutely has a huge impact of routine distances travelled and total miles driven in a day. If there's a corner store at the bottom of my 40 story tall apartment tower instead of driving a few miles, it changes your travel distances considerably.
> the average trip in the US is less than 20km
I don't buy my car for my 50th percentile drive. Probably 60% of my drives are less than 10mi. I'm not going to buy a car that only gets me 20mi though. I'd rather buy a car that meets at least my 80% needs on range. I'll deal with charging on long road trips, but until there's at least a good number of chargers locally where I'm almost guaranteed to be able to charge at the destination if on one of those 75-80th percentile drives I'm going to want plenty of charge to go there and back again without needing to stop in the middle, even if only for like 10 minutes or so.
Also, when talking area, you're comparing Atlanta proper to Shenzen. You should really be comparing the Atlanta metro area (21,693km²) or the LA-Anaheim-Riverside CSA at 87,940 km². China doesn't really do the same thing as the US with tons of smaller cities surrounding a small central city, they largely just have the one big city.
Don't get me wrong, I'm in agreement that people generally don't need 300+mi range on their cars, Americans tend to drive massively oversized vehicles for their needs, lots of urban design in the US has been pretty trash in the end, etc. And yeah, I'm in agreement that a Renault Zoe, with ~250mi of range, could suit most Americans. That's still 2x more range than a Tiago.ev, and the Zoe is still quite a big larger.
Thinking the Tiago.ev would be widely accepted in the US, in its current climate, is a fantasy.
