"Normal use" being "I forgot to get gas last night, I wonder if I have enough to make it to work and stop on the way home". Less likely for a car that gets plugged in every night and has enough range for 3-4 days, but more severe since you'd be at least 30 minutes late instead of 5 minutes.

This is mind-boggling, it's like every comment starts a new, out-of-context discussion. The context here is someone purposedfully continuing to drive the car after it's empty and the "car bricking under normal use" comment. In your example it wouldn't be bricked.

why would it be unreasonable to test that in a review?

it's not, but it is unreasonable to not mention it if you did it.
