Not an Elon fan, but gotta say Teslas are pretty dang safe and cool from everything I've read. My newer VW Jetta is also incredibly safe and I ADORE it. Back-up camera, beeps when I'm in reverse and ANYTHING (kid, dog, car) is behind me, the side mirrors have a light that goes on when someone is in my blind spot. Loooove it as a person with bad RA in my neck and shoulders. I've also read that they're good in accidents (I mean, nothing is good in an accident, but the car is safer than many).
It's an interesting way he chose to try & kill his family. Definitely Hart-family inspired. Did he plan to also kill himself?
