Ken Johnston is excited about the "flash and hype" for Tesla's (TSLA) weekend rollout of its Robotaxi capabilities. He believes Tesla is focused on the long game, and says Elon Musk's company holds the upper hand with its established software-defined vehicles. Yvette Zhang says the autonomous driving market is estimated to grow at 11% year-over-year, but adds that Robotaxi is more regionalized because of legislation restrictions.
