I can think of only a few situations where you'd want to get out of a car quickly, where you'd have enough time to look under all the matte covers to find a manual door release switch that may or may not be installed. A fire is certainly not one of them. At the very least shouldn't they be equipped with a Nothammer...?
tesla gonna tesla so I assume they are as dangerous as can be.
For the rest? There is always (?) one window that isn't reinforced. So that CAN be an issue if your cabin is significantly damaged. But otherwise? It is a problem to find in a high adrenaline emergency and you SHOULD be aware which window to smash, but you are 3-6 smacks away from being out.
