Sweet baby jeebus you all are reactionary as hell today. Did some of you manage to forget your meds?

Anywho, it's not a bad thought. IIRC, aerodynamic requirements for vehicles currently exist as a compromise. What works well at low speed isn't necessarily good for high speed, so having a vehicle that can be adaptive is likely a good thing.

BTW, here's another link without the YT smarminess.

As for the nonsense in the post from others:

• It's very possible to have a tear resistant fabric or flexible material that would allow for durability.
• It's also very possible to have a flexible outer surface AND have actual aluminum/steel/fiberglass underneath that to protect from penetration.
• This is a concept vehicle, and probably an expensive one. It's also a convertible. I wouldn't be worried about the whole "penknife break-in" scenario. Windows don't offer all that much protection, nor do current fabric convertible tops, yet vehicle owners manage to continue to get by just fine.
• It's easy to design a cage that doesn't depend on the vehicle's skin to any large degree while still protecting the occupants. Might make fixing crash damage more costly, but it's certainly doable.
• Even if it did end up being a death sentence, those people chose to purchase said vehicle anyway. They need to do the research themselves - can't pin everything on the manufacturer and absolve the consumer of all responsibility for their actions, now can you?
