You will NOT understand how hard it is to break a car window until someone is burning behind it.
A similar thing (burning car) happened not far from my house a few years back, she didn't make it despite 2 broken hands trying to bust the window.
Car tech is both good and bad sometimes. Of course when you start rolling, the car/truck auto locks the doors. Now... someone please send auto manufacturers an email to put in a smoke or temp sensor, so if the car is on fire, the doors unlock.
Watching someone burn to death is some of the stuff nightmares are made off.
