I’ve had a Ford (mid range SUV) and a Toyota (base model sedan) which were both damaged whilst parked, and nobody left a note. Lots of people posting in the community groups about carpark damage and no notes being left, and no luck with local cameras.
So yes, it is needed.
It’s not specifically “the” bar, but the original comment was saying they didn’t see how Tesla would even be considered, and I felt this feature is one reason why someone may still consider a Tesla.
For me, my dash cameras have come in handy when my vehicle was running, but the hardwire mode has not been able to handle what I wanted it to. I want my next vehicle (whenever that may be) to be an improvement over what I already have. I have personally had my vehicles damaged more than once whilst it was parked, and I have always parked well. Sentry mode would have been very bloody useful to have the responsible parties pay up. Instead, I was left with a damaged car, which was notably rather heartbreaking when one incident occurred within the first month of ownership.
EDIT: My motorcycle was hit and if I hadn’t had known, I wouldn’t have been aware enough to take it to the shop to be inspected in case any of the internals had been damaged. Sometimes damage can be internal and without an alert, you would be putting yourself in danger.
