It sounds like you're referring to the Tesla Cybertruck unveiling event in 2019, where a prototype vehicle's window shattering incident occurred.

The Cybertruck is an electric pickup truck designed and manufactured by Tesla. The prototype was indeed unveiled at an event in Los Angeles (not Trump Las Vegas) and later in London. However, there wasn't any incident of the vehicle being blown up.

It's worth noting that the Cybertruck event did feature a demonstration where the windows were shattered when a steel ball attached to a taser-like device was fired at them. This was part of a planned presentation showcasing the strength of the glass material used in the truck.

Regarding your comment about Teslas snitching, I'm not aware of any specific incident or feature related to that.
