Looks like crash tests are still going on. These Karma's with crash test stickers on the side were spotted in The Netherlands, after having met their executioner (judging by the missing parts and what looks like some damaged parts, but I'm not sure).
I am sure they have done well or will do well. Most of the testing is done 'virtual' nowadays, so the real tests usually don't produce any surprises. Unless you're a Chevy Volt ofcourse, and are being left unattended for three weeks with the battery still connected.
