Lane departure warning activated and attempted to correct during a gentle curve. The location had shifted lanes due to construction, so clear lines were visible but not the actual lane to follow which is a frequent occurrence in New York City. The system came close to steering me into the adjacent lane occupied by another vehicle forcing me to fight the correction. There was a lane departure warning on the dash and I believe the blind spot indicator was on (i.e. the adjacent vehicle was detected in some capacity). I considered this especially dangerous as in this zone also had very tight lanes so my physical correction could have also caused an accident. There was no malfunction of the physical components. No dealer or service center has reproduced the issue however I have discussed with other drivers of the same line (2020-23 Mazdas) who have had similar experiences leading to a decision to disable these "safety" features. Mazda provides a reasonable description of scenarios where lane departure and assistance will disable itself due to poor conditions or low confidence. I would recommend at a minimum requiring the system to detect and potentially differentiate lane widths, as city driving sometimes has extremely tight lanes (for example, the inner roadway of the Williamsburg Bridge where two adjacent lanes are perhaps 8-9ft with less than 2ft on either side to the wall). In these scenarios, any steering correction at all is more dangerous than if it were off.

My new 2020 Mazda 3 premium with 1,177 miles suddenly took complete control of steering my car. Driving 65-70 mph on a 3 lane straight highway on a clear day, with light traffic, I moved one lane to my left, and the car took over the steering, pulling my car out of the left lane nearly missing the center cement divider, then darting back across my lane and halfway into the lane to my right, then dashing back to the cement median. I am unaware of how many times the back and forth occurred, I tried to slow the car down to no avail. The car was moving fast, and the pattern the car moved in was very precise, as if the car knew not to hit the median and go further into the lane to my right. Finally the car stopped steering itself, and I was able to exit the highway. My car was not damaged. I hit my head twice on the drives side door. I did not require medical assistance.
