News recently has been focused on the announcement that Tesla will no longer be equipping their vehicles with radar and that the company's Autopilot suite will soon be replaced with its "Pure Vision" system consisting solely of cameras.

Reasons proposed for the change include possibly a shortage of availability of components to continue supporting a radar system, that it is a cost-cutting measure particularly with the lower-priced Tesla cars in mind, and/or that the camera-based system is so good that radar is not really needed.

Be that as it may; however, it appears that not all of the bugs involved in current vision functionality have been adequately addressed. In particular---the high beam issues some owners report while using Autopilot.

What's Going On With The Auto High Beam Function?

Just yesterday Reddit member Jaws12 posted that after picking up his brand new Model Y in Cleveland, he discovered that Autopilot essentially forces the owner to have the Auto High Beam function enabled while on Autopilot.

Here is the Reddit Jaws12 post below and what he saw on his screen from Autopilot:

The automatic high beam function in Tesla and other makes of vehicles are designed to engage the high beams when oncoming traffic is no longer detected, and then turning them off once an oncoming vehicle (or approached vehicle) is detected by the vehicle’s vision sensors.

In other words, you are driving with high beams on all the time presumably because it offers a better view of the road ahead. This is in contrast to traditional driving habits when drivers were encouraged to drive primarily with their low beams all the time except in times of reduced visibility. The exception of course is to dim the headlights when blinding another vehicle is imminent.

The post seen in Reddit was surprising to me in two ways: (1) I thought that High Beam issues were an old problem fixed previously with updates. (2) This might not be a software/function issue, but is possibly designed this way because engineers decided a “Motherboard Knows Best” approach was needed. In other words, the view that Autopilot is a better judge of lighting conditions than the owner is.

Problems with the Auto High Beam function with Autopilot are not new. A quick search back in time reveals that while not everyone has experienced problems with the High Beam function on their Teslas, others have reported repeatedly flashing headlights, erratic High Beam on/off behavior, etc. It appeared that environmental conditions such as reflective road signs, vehicles with skewed headlight alignment and commercial vehicles with relatively higher sitting head and tail lights confused the sensor response.

Software updates appeared to be the solution and took care of the problem. Until now.

However, with the Reddit post that a brand new Model Y is experiencing an Auto High Beam requirement in order to use Autopilot, it seems odd enough to believe that perhaps it’s not a software or environmental glitch, but something else.

According to a following post by Reddit member Respectable_Answer, it may just be a matter of a band aid fix until the next upgrade in Tesla Vision happens.

Please let us know in the comments section below if you have had any issues similar to the Reddit Post or if you have found that the Auto High Beam function has always worked fine for you. Plus, what are your views on a “Motherboard Knows Best” scenario? Should we accept loss of control of features because some may view who or what is the better driver?!
