There's so many variables. Car can get crushed where doors on one side can't open. I'm not sure if you have climbed from the front to back or visa-versa in a car but it's actually pretty awkward, and most people are fat and out of shape. Add in initial shock & pain after a crash and even worse the panic if the car is on fire.Yea, I feel like if you're more familiar with some kind of mechanical latch to open the door, that's what you'll be drawn to, not a button. Then the folks in the back could climb out the front. If I was rescuing my young kids from the back I'd probably be more likely to reach back from the front and pull them out the front doors.... Maybe. I dunno... I guess if there were older folks that can't move around to well, they'd be f'ed from the backseat...
I just skimmed the article and the only details of the accident were that someone was able to pull a young woman out after breaking the window. There were 4 other people in there? Were they knocked out after the crash? Were they trying to get out? Would they have been dead anyway if the car didn't catch fire?
That Tesla caught fire. So the people inside post-crash had to quickly figure their way out which clearly is much harder for backseat people if there's no power and they never had to know about the backup method. Car fires can quickly go from minor to major, more so when there's the Lithium batteries involved.
