I love Tesla, but Musk's starting to smell a little like Peter Molyneux -- promising the world and delivering little. Get the Model X out (2 years late and counting...)
It's certainly not the plain reading of "the self-driving technology was 'technically capable of going from parking lot to parking lot,' meaning through cities as well."
If what all that actually means is "adaptive cruise control + lane keeping," then either the GP poster is right that Musk is overpromising and underdelivering, or the journalist completely misconstrued Musk.
