The manual door open on some models of Teslas require removing 2 panels that are not labeled and need a diagram to know how to remove them. Another requires removing the speaker grill and pulling an unlabeled wire.
Even once the manual door release is pulled, without power you need a firefighter's upper body strength to open the door, and it's likely that flames and poisonous smoke will be coming up any tiny gap you can create by pushing open the door a little.
Just willful disregard of your customers' lives.
