I am excited to take delivery of my Model S sometime in the next couple of months, as Autopilot 2.0 was far more than I was expecting from Tesla at this time. That being said, I thought it would be interesting/fun to discuss the differences between Volvo's approach and Tesla's, seeing as both chose the same autonomous driving computing platform. While both systems are powered by the Drive PX2, the sensor suite chosen by each is quite different: Tesla: 8 cameras, 1 radar, 12 ultrasonic sensors Volvo: 5 cameras (including 1 "trifocal" camera), 7 radar (4 surround radar and 3 long range), 12 ultrasonic sensors, and 1 LiDAR Also, while we aren't yet sure what the redundancy is in the Tesla, Volvo states that all critical systems have a backup including the computer, sensors, steering, and brakes. It seems that Volvo has a more robust sensor suite whereas Tesla is going to be more camera-dependent. The details of the Volvo solution are described here: Self-driving car test | Intellisafe | Volvo Cars Drive Me, the world’s most ambitious and advanced public autonomous driving experiment, starts today My worry is that Tesla may not have the redudancy necessary for regulatory approval of their L5 platform, and they will be forced to issue an updated autopilot hardware suite to conform to regulations. Here's an example: if one of Volvo's side cameras fails or gets blocked with snow/debris, the radar should be able to serve as a reasonable backup to keep the car safe to pull over or let the driver take control. The Tesla, on the other hand, has no side radar and so would need to rely on the very limited ultrasonic sensors in the same scenario. From what Elon has said, Tesla has tested this platform for a year, so I am sure there is more to the story. For Tesla to advertise full autonomy, there must be everything necessary for level 5 in the car. Hopefully we will learn more about how the system works and the backup systems in place as time goes by.
