Tesla's autopilot, on the road
Back on-topic, the article below reviews the contrasting philosophies of how autonomy may be introduced to vehicles, as a series of features added gradually, or as a completed product able to drive a car:
What Tesla and Google’s Approaches Tell Us About Autonomous Driving
U.S. transportation authorities are investigating the deadly collision of a Tesla Model S car. And many reports say the fatal crash has heightened concern about self-driving cars. Which may be true. Except — Model S isn’t a self-driving car...
CEO Elon Musk’s approach with Tesla is to roll out Autopilot (a sort of highly advanced cruise control) and other autonomous features like self-parking with software updates over time...
Google instead is focusing on creating a fully autonomous car, all at once, and isn’t selling any of them. That means it’s lagging behind Tesla on driven miles, but they don’t involve regular drivers. (Tesla says Autopilot has been activated for more than 130 million miles, while Google’s website says its self-driving cars have driven 1.5 million miles.)
Technologically, the approaches differ, too.
Google relies on a highly expensive complex remote-sensing system called Lidar..
Musk late last year suggested in a press conference that Lidar was a bit excessive for an automobile..

On that subject:
FRANKFURT -- Self-driving cars will need multiple detection systems including expensive infrared "lidar" technology if they are to be safe at high speeds, the CEO of German auto supplier ZF Friedrichshafen said today.
Stefan Sommer's remarks come a week after news that a 2015 Tesla Model S crashed into a trailer while on Autopilot mode. Tesla has said it was hard for the car's cameras to identify the white trailer against a bright Florida sky...

As I posted last April, Nissan plans (or at least before the autopilot crash reports began, had planned) a gradual introduction similar to Tesla, but with a much more cautious timeline.
As the video below shows Nissan has already prototyped much more advanced features than Tesla's autopilot, including city/intersection autonomy, but it will be years before we will be able buy vehicles from Nissan with all these capabilities:
