Sure, you are in control of your Tesla but you are obviously not in control of other Teslas. Someone else who isn't as diligent as you or who doesn't care about it's limitations will happily crash head-on into you, blissfully unaware of their own ignorance.
I'm not in control of any other cars on the road. Many of those cars are driven by drunk, distracted people who cause thousands of deadly accidents every single year.
