The batteries would have a longer life, but they don't have the stamina of Li-ion batteries. The range for nanosafe batteries in EVs is 110 miles or so.
The 10 minute charge time is definitely an eye opener, but when you realize it takes 440V and huge capacitors to power the charging unit, a home based charger is out of the question.

The batteries are warrantied for 100,000 miles. After that, it's close to $10k to replace it. There are individual modules inside the main battery pack so "collecting" some as time goes on would be the best bet instead of shelling out 10 grand for a set later.

The motor is a 3-phase AC unit. What are the downsides of multiple batteries and regenerative braking? I understand the multiple points of failure among several thousand cells, but I'd rather have a row go out than a complete module.
From an electronics background, what would you do differently?

EXACTLY! I just saw on the news while I was at lunch that truckers in London are protesting by parking their rigs in the middle of traffic. They're paying approximately $10USD per gallon over there for diesel.
The Tesla Roadster is the first EV that has comparible acceleration, top speed and range to todays gas burners
and it looks GOOD.. Yes, my truck has a 410 mle range, but my RX-7 had a range of 260 miles or so which is not far off from the Tesla.
So far the Tesla is unique in that besides the comparisons above, it can be charged from any standard electrical plug from 110v to 220v and comes with the umbilical to do so. If you drive 150 miles to work, park it, plug it in and drive it back home in the evening.
One problem with bikes or bike-based cars like the Ariel Atom - bad weather.
I'm kinda pro-Tesla for a couple of reasons... #1. Nikola Tesla is one of my heroes. #2. A car like the Tesla Roadster HAS to take off and become a hit before we see cars, even hybrids, utilize more electric power and less gasoline.
I like ICEs just as much as everyone else, but when I sat down and looked at the numbers the other day I realized that I spend on average $700 per month in gasoline, where
10 years ago I would use $200 in fuel for the same amount of travel.
That's just silly. Ten years and it's almost four times as expensive.
