How did you verify that a software update can 1. Occur during driving operation of the vehicle and 2. results in vehicle power loss?
I worked in an auto supplier years ago and there where several protections in place to prevent the risk of update corruption on safety related components. One of the simplest one the UDS programming session having entry protections related to vehicle speed, vehicle driving mode, etc.
My update occurred while parked. I hit the failure mode 1-2 hours later pulling out of my driveway.
