Yes, but there is usually an additional system like Toyota's Safety Stop which WILL detect a stationary object and kick in at the last minute to reduce speed by N MPH before collision.
AFAIK Tesla used to have that via its RADAR but because the new production has no RADAR, new cars can't have it, and they disabled it on the older cars too, in the interest of using a single software version.
At least this is what I've gathered from reading here and elsewhere.
- modeless 5y agoRadar is useless for detecting stationary objects because of far too many false positives. Radar is the reason why these warnings exist. It is not the solution. Teslas continue to have forward collision warning and automatic emergency braking as standard features whether or not they have radar. But again, they do not detect 100% of all stationary objects and neither does any other automaker's system.
- raylad 5y agoThese systems do work and have worked for years. They are also regularly tested by IIHS. See, for example: https://www.youtube.com/watch?v=TJgUiZgX5rE https://www.youtube.com/watch?v=TJgUiZgX5rE And Teslas at least used to do this too: https://www.youtube.com/watch?v=aJJfn2tO5fo https://www.youtube.com/watch?v=aJJfn2tO5fo If they no longer stop reliably to avoid hitting stationary objects, this is a serious problem that needs to be corrected.
- modeless 5y agoThey absolutely work but they are not reliable. Not on any car. They are a safety system of last resort.
