The camera alone seems to see a lot: - 2018: https://youtu.be/_1MHGUC_BzQ https://youtu.be/_1MHGUC_BzQ - 2021: https://youtu.be/XfqabC_akV0 https://youtu.be/XfqabC_akV0 Is the car reacting to what it's seeing? Probably not, but I'm not sure if adding a lidar fixes that.

> The camera alone seems to see a lot: In perfect conditions, on a sunny day. I'm in Sweden, and the sun shining directly into your eyes from barely above the horizon while the road is wet/covered with snow and reflects that sun at you is a regular occurence during winter months. I odubt Tesla's camera will be able to see anything.

  This is the reason why a single camera alone is not capable of being the sole source of information for a self-driving system. The technology currently available for camera systems does not capture a high enough dynamic range to be able to see details in darkness when the Sun in in frame. You could use multiple cameras all with different sensitivities to light and combine them, but it's going to be very difficult.

    Why would it be very difficult? You can split the same light beam after the lens, and send it to two cameras with different diaphragm or sensitivity. You'd then synthesize a perfectly aligned HDR picture.

      I think you two just proved my point

    I really don't see what's difficult. You don't even need multiple cameras, you can simply use very short exposures and combine short exposure shots into a longer exposure one when needed. Multiple cameras are useful to handle glare though.

Its because Tesla cars are regularly causing "phantom braking" events. Tesla is trapped between a rock and a hard place. Their "phantom braking" events are causing a lot of dismay to their drivers (https://electrek.co/2021/11/15/tesla-serious-phantom-braking-problem-autopilot/ https://electrek.co/2021/11/15/tesla-serious-phantom-braking...). But if they reduce phantom-braking, they increase the chance of hitting that child on the road.

  Elon claims that the radar was the primary source of phantom braking. He said that matching up a high fidelity sensor (the cameras) with a lower fidelity sensor (the radar) was proving near impossible. I also suspect the supply chain pains massively factored into his decision to remove the radar from all vehicles since roughly late January of last year.

    Anyone in the car industry would know this as obviously false? Radar based emergency breaking is availability and works really well in many cars from 5+ years ago.

      I’m not debating the validity. This is literally what Elon said.
  - dragontamer 5y ago
    Radar was removed in May 2021, which predates the article I quoted by multiple months. I'm sure Elon was blaming Radar for phantom braking in the April / May time period. We can give a few months for the cars to update to the newest version as well. But by November 2021, RADAR was no longer a relevant excuse. I think you may be mistaken about when Elon said what and when. You gotta keep the dates in mind.
