Indian-American technology entrepreneur Vivek Wadhwa in an as-told-to essay to Insider called Tesla's self-driving software "dangerous", and said, "Elon Musk made a bad decision to discontinue using radar in Tesla cars." He wrote, "I used to call him a friend." He added, "I've had three Teslas...and it's still the only car I drive...But, my next car won't be a Tesla."
