Its a few hundred gigabyte. You can only login with an institutional account. My research institute is very small, can I borrow someone's login credentials? (email in profile).

Can someone show what the most aerodynamic cars in the dataset look like? Does it specify the drag coefficient? Curious to know how many of the 8000 shapes reach < 2.0, should be at most a handful.

Somewhat related: Can someone tell me why all those new electric cars are so poorly designed in terms of size and weight? Most of them weight over 2t and have a large frontal area (VW ID.4 is the prime example). I just want an economical family vehicle (lightweight, hatchback design) and there aren't that many options. Isn't that something loads of people want or am I the exotic one?
