Someone with more experience should step in and correct me but my understanding is that this is how we used to do things and stopped because it turns your passengers into soup. You need those parts to crumple. I'm sure Tesla has thought of that and wouldn't downgrade the structural safety but it does mean the new design is probably just as easy to damage but more expensive to replace than traditional designs.
- spockz 5y agoI suppose you want the crumble zone to be on the outside. Outside critical parts and easily replaceable. Then you want the inner shell not to disform, or not too much, as otherwise you are sending metal into body parts.
- HPsquared 5y agoCars are designed with a strong central structure (passenger cell) and weak areas at the periphery (crumple zones). These cast parts are in the "strong" area, I think.
- _ph_ 5y agoThe crumple zones are unaffected by the casts and the casts can crumble as well. But if the car gets deformed beyond a certain point, it would be totalled anyway. If you look at pictures of the casts, the front ones mount the wheels but end there, the rest of the car ahead of them is made from sheet metal and metal bar with the purpose of crumbling easily.
