Why Tesla's Full Self-Driving software is so controversial

One of the first things to know about Tesla's Full Self-Driving (FSD) software is that it doesn't make cars fully self-driving. Shoddy on-road performance, misleading branding, and false promises from Elon Musk have landed the $10,000 semi-autonomous feature in hot water with safety advocates, regulators, and Tesla owners themselves. Still, Tesla plans to roll out a prototype version of FSD to thousands more drivers, further fueling questions about whether it is safe enough for public roads. Autopilot, which comes standard in Tesla cars, is essentially cruise control with the added ability to navigate curves in the road and adjust speed based on the vehicle ahead. FSD -- which buyers can purchase through a $10,000 one-time fee or a $199-per-month subscription -- adds the ability to automatically change lanes, enter and exit highways, recognize stop signs and traffic lights, and park.
