Oh I forgot 1 other very important data point which suggests the accident was not intended by the valet...unless of course he was suicidal. He wasnt wearing a seatbelt! That's 100% accelerator downpressure, or pedal to the metal, no seatbelt, in an enclosed space, & no signs of flinching before impact. Either this is one crazy & ballsy valet or this is the perfect example of sudden acceleration.
