63000*33*.33/(3854*0.9)*84000 = 16,782,563 lbs or ~7,600 metric tons worth of batteries for 1 day's worth of "electric fuel"

Bumper height plays a far bigger role in pedestrian fatality than hardness of the vehicle shell. Cybertruck's bumper is significantly lower than pretty much every other pickup truck out there.
The fuel savings are dramatic in Washington with our low-cost electricity and relatively high gasoline prices. For example, I pay $0.11/kWh and EVs get 3-4mi/kWh. so thats about 3 cents per mile travelled.
Assuming 30mpg and $4/gallon, that's 13 cents per mile travelled or more than 4 times the cost per mile. And there are plenty of ICE vehicles that get less than 30mpg and gasoline is often more expensive than $4/gallon
True, last year it wasn’t but this year it was the best selling vehicle of any type, EV or not, including trucks.
But you’re right that comparing largely highway miles vs all miles isn’t completely fair. FSD on the other hand can be activated and used in most scenarios and has 3.2 million miles between accidents vs the US average of 500,000 miles. So still quite a bit safer but less so than autopilot.
As for autopilot deactivating right before an accident, if autopilot was active within 5 seconds of the accident it is still attributed to autopilot, not the human driver.
But I'd like to point out that the link you included is out-of-date. Tesla has continued to publish their autopilot safety numbers in their quarterly slide decks. Here is Q3 2022 for example, see page 10: https://tesla-cdn.thron.com/static/SVCPTV_2022_Q4_Quarterly_...
Miles between accidents on Autopilot Q4 2021: 4.3 million miles Q1 2022: 6.5 million miles Q2 2022: 5.1 million miles Q4 2022: 6.2 million miles
Here is 30kWh of LFP batteries for $9,000. Now that doesn't include the inverters or installation or anything but LFP batteries have excellent longevity, in this case 7000 cycles to 80% depth-of-discharge. That means charging and discharging the battery every day for 19 years and at that point, you still have 80% of the remaining capacity.
