If you look up crash ratings, you will find it's not uncommon for new car models to be missing them. It just isn't something that is done before the first unit is sold - presumably because as other people mentioned, it has to be done independently to be useful. Of course there must be internal tests, but there's no use in publicizing them because of the conflict of interest, and I'm sure if Tesla did that, people would point out the problem.

People who are concerned about Tesla unwittingly give away the fact they don't browse the IIHS web site for fun. It is educational.

If you search for the Honda Insight on said IIHS site, you will find the old one that ceased production in 2014, not the new one that just arrived at my local Honda dealer. This is not shocking if you had any interest in the subject independent of Tesla.

The NHTSA site lists the 2019 Insight, but surprise, surprise, it says it is not rated.

Because the company that is responsible for crash tests hasn't bought the car yet?

They have to buy cars in the market to prevent manufacturers from adding reinforcement

That was my takeaway from the article. Why on earth are cars being sold which haven't gone through proper safety testing?

maybe for parts only, nobody will drive that thing as-is anyway
