Interesting. Tesla seems like a lot more cumbersome vehicle to perform dash evolution/extrication due to the presence of the high voltage battery. for example, in a traditional vehicle, a dashbeam blowout is performed using a higher speed ram. Without this, you have to make 3-4 more cuts to the vehicle https://www.youtube.com/watch?v=-n65nm5yQKs https://www.youtube.com/watch?v=-n65nm5yQKs Tesla model access for the rocker channel is also inconsistent and a little scary. Rocker cuts made to the X for example seem to be permitted, however in the model S they might be lethal. I really wish they had more in the series on this. disclosure: I was a volunteer firefighter for a few years after highschool.

What's a rocker channel?
- dsfyu404ed 7y ago
  Rocker panel. Edit: Why is this down voted? It it literally the same thing. The firemen may call it a channel (and the sheet-metal is roughly of a shape that people in the metal industry would refer to as a "channel") but the terms are interchangeable, it's the lower outboard edge of the passenger cabin.

    It’s not a very informative comment. The obvious next question is: what’s a rocker panel?
    - dsfyu404ed 7y ago
      That's an easily answerable question. Everyone here has an internet connection. Swapping an obscure term for an industry standard term should be enough to make search engines useful. If I wanted to spoon feed people I'd go to Reddit.

        A brief description of the component in question would be appreciated. One of the benefits of describing what a rocker panel is in your own words, or even quoting and providing a reference, is that it encourages discussions here. From what I've been reading this morning the rocker panel is the structural and component of the vehicle immediately under the side doors, and also includes the visible panel. Is that a good enough approximation? If you're able to provide more information that'd be great!

Considering that Tesla's cars are significantly less likely to flip, significantly less likely to catch fire, slower to burn when they do catch fire, and the safest cars ever tested by the NHTSA ...is it fair to say that the added extraction complexity is somewhat of an acceptable trade-off?

  >significantly less likely to catch fire, slower to burn when they do catch fire Citation please. This directly contradicts the anecdotal experience of literally everyone I know who deals with crashed vehicles (10 < sample size < 20, ~66% tow truck drivers). Compared to other EVs Teslas definitely seem to be the most flammable. Everyone who handles crashed cars seems to regard a mangled Tesla as a hot potato unlike a Prius, Leaf or ICE car. The NHTSA stuff and crash safety I believe, that's well documented by reputable sources (e.g the NHTSA). Nobody except Tesla and their fan-base seems to be saying EVs are less flammable on a per crash basis though and even then nobody says point blank that crashing a Tesla is less likely to result in fire than crashing something else. Edit: I am specifically talking about the likelihood of fire per serious crash. Not average number of fires per vehicle or per mile.

      Maybe the fact that rich, educated people drive Teslas, and poor, uneducated drivers don't accounts for it (my hypothesis is that rich, educated drivers have fewer accidents on average since they are less likely to DWI, etc)? To control I would want to see what % of Tesla crashes catch fire compared to ICE crashes.

I'm not sure what ram speed has to do at all with extrication. The biggest problem area I see with the model 3 is the fact that a large portion of the high voltage carriers are centerline on the vehicle. In our department using the center post for dash lift/roll allows us to work both front seats without obstructing patient egress via the side/door. In the Model 3 you don't have the option to roll from the center.
