> And yet every Tesla owner tells me that their car is just one update away from driving itself across the country.

I just drove my Tesla half way across the country and back last week. And based on the performance of Autosteer and the neighboring car visualizations they're nowhere close to Level 5 self driving.

Love the car and am a big Tesla/SpaceX fanboy. But I won't believe it'll achieve Level 5 until I see it.
