Sam is back with Leo to talk about a new car cockpit design which has a steering wheel that receeds into the dashboard when the car drives autonomously. The new design also uses the actual surfaces of the car to act as car stereo speakers. Any surface you can get to vibrate can transmit sound thanks to actuators. You can even embed them in the seats. The potential also exists to create "sound bubbles," which would let you listen to something, while other passengers are listening to something else. But without headphones. Leo says that it's a lot like computational photography, but with audio.
