At least the semi-truck driver stopped.
Luckily, the actual wreck is less severe than you might at first think. We envisioned the semi backing into the Model 3 or perhaps entirely sideswiping it. Instead, the truck driver just seems to have misjudged the trailer size a bit and cuts to turn a wee bit too early.
It appears to be a grazing rather than a hit, but yes the Model 3 is damaged and yes, Sentry Mode captures it once again. It could've been a much worse outcome, Such a valuable feature that Sentry Mode is proving to be.

Wed 5th of June 2019 at 13:50 I parked to go see a friend at his office and came back 15 minutes later to find my car damaged and a few people that had stopped the truck driver.
