> So then why not warrant against it if this is so certain?

They do. 8 years / 100,000 mile warranties suggest that ~3 sigma lifetime is at that level. IOW, Tesla likely believes that >99.5% of all cars will not need a warranty battery replacement by that point. To hit that level, the average car needs to do a lot better than that.

If measured in miles/tank, they definitely do. The gas mileage a 10 year old car gets is worse than the same car when it was new.
