All hood latches from all brands are double latched. You're not going to get a hood flying open unless both latches fail. If one is open you want to close it ASAP so you're not driving without the redundancy. But it's not an immediate hazard.

These are probably cases of the second latch "failing" or not being able to hold the hood closed at X mph and Y windspeed when the driver fails to latch it all of the way.

Not on a Tesla (1990-something...), but I've had a hood latch "fail" because I didn't close it all the way. Got on the highway, enough wind got under and the hood slammed open, wrapped over the roof and shattered the windshield but luckily safety glass held it in place. I didn't think hood latches had industry safety standards past the latch and common sense.
