This situation does reinforce the fact that even during your everyday course of driving to work or wherever, you should always keep at least a good 1-2 car distance between you and the car in front of you when slowing and stopping to leave an emergency exit route if something like this goes down.
Drivers box themselves in in traffic constantly, never thinking that now they can’t back up or move forward to provide themselves a route out of a bad situation. They don’t think of it or pay attention but this is def a good learning point for that alone. The idiot behind you will most likely be right on your rear bumper so it’s up to the aware and alert driver to leave some space in front to be able to punch the gas without needing to work the steering wheel over and over to just get the hell out of Dodge in a hot minute.
