         | 2021 Toyota Corolla owner here .. it works well enough, but
         | random reflections off of street signs and such cause them to
         | randomly flick on and off. I wouldn't call high beam assist a
         | "safety feature", but more of a "hey, it's better than
         | nothing". I tend to use my high beams more in scenarios where
         | it would have been too annoying to turn them on and off, so
         | it's net safer. If that makes sense. I wouldn't classify this
         | article as news ... it's sort of a given that this technology
         | is a bit iffy?
         | 
         | For that matter, the Toyota lane keeping is one of the better
         | and safer ones that I've driven, but it flakes out and gives up
         | way too easily to rely on (a small gap in the line and it
         | disables, as opposed to trying to push you into curbs). Again,
         | just a "better than nothing" experience that can be useful on
         | the tail end of a long drive. In the case of Queensland ->
         | Melbourne, the car was the better driver at the end.
         | 
         | The street sign reader, speed warning and rear cross assist is

       | Things like this (and panel gap, and build quality, and over

       | will probably seriously re-evaluate them for my next car

       | 
       | BTW, I got my first demo of tesla FSD a few weeks ago. In san
       | francisco, on market street, a place I'm sure is tested
       | extensively. Within minutes, FSD had the car perform an illegal
       | AND dangerous mid intersection merge followed by an extremely
       | hard and jerky lane follow correction. lol.

         | the key fob wouldn't communicate with the car and refused to
         | start. The emergency break also suffered a software failure

         | spot on. Whew.

       | wipers on and off. Frequently it just keeps wiping a dry window,

       | multiples times. Usually a bunch of times a week. Just for
       | funsies. - Garbage night AP performance. Car coming in the
       | opposing lane with its lights on? Better slam on the brakes. -
       | Garbage bad weather performance. Just a bit of rain or snow and
       | even TACC can't go a reasonable speed.
       | 
       | A whole lot of this probably comes down to the lack of radar or
       | other sensors. And the lack of ability for them to get machine
       | learning with only cameras to perform.
       | 
       | Maybe they should just send the engineering team up far north
       | during the winter and force them to dog food their software to
       | get around. Really it's not the individual engineers fault, it's
       | always crap management.
