Self-driving car technology. SAE Levels 0-5: Level 2 (Tesla Autopilot, GM Super Cruise), Level 3 (Mercedes Drive Pilot 2023), Level 4 (Waymo, Cruise robotaxis), Level 5 (full autonomy, unrealized).
Early Hype (2015-2018)
Tesla “Autopilot” (2015): overpromised, underdelivered. Elon predictions: “Full Self-Driving next year” (every year 2016-2024). Waymo (Google X, 2009+) methodical approach.
Reality Check
Level 2 = driver assistance (adaptive cruise, lane centering). Level 3 = conditional automation (Mercedes Drive Pilot 2023, 40 mph max). Level 4 = robotaxis (Waymo Phoenix/SF, Cruise SF 2022-2023).
Waymo Success
Waymo One (2020+): driverless rides Phoenix, San Francisco. 700K+ rides/month by 2023. Jaguar I-Pace fleet. Slow rollout, high safety record. “It actually works” validation.
Cruise Disaster (2023)
GM Cruise robotaxi dragged pedestrian (Oct 2023), covered up details, lost permits, CEO resigned. Industry setback. “We’re not ready” reality.
Cultural Phenomenon
#AutonomousVehicle = techno-optimism (2015-2018) → skepticism (2019-2022) → cautious progress (2023+). Tesla FSD Beta “drives itself into oncoming traffic” viral fails. Waymo “it just works quietly” contrast.
