Except their car autonomy (autopilot, full self driving). These "features" work poorly and are dangerous. They've been trying to get it right for almost 10 years and keep promising "by the end of the year" but they still are not ready for prime time. I think part of the problem is that they are stuck using "vision only" whereas other autonomous car systems use a combination of sensors (vision, ultrasound, radar, lidar, etc.) which seem to work better.
OTOH, the frequent software updates have improved many other aspects of the car.
