Yes I agree, I don't follow street cars near as close as I do race cars, so I was ignorant and too busy at that time to G it. TBH I am fundamentally adverse to self-driving cars (though I'd love to race against their future counterparts, but alas I'll be too old) but I am not a Musk hater-I find it astonishing that he can land a rocket on a barge. I am happy to hear he sought out expert advice, and now thanks to you, I have to look into that more myself :)
