Yes, few weeks ago. Is TJA and Assist Plus different? Can TJA work on local street traffic under 40mph? Assist Plus came on multiple times while in traffic on Highway 80 near Vacaville.
TJA and Assisted Plus are the same thing. I don’t think it works on local street but cruise control actually works on local road it follows car in front but won’t steer.

Yes. If you are in Assisted Driving mode, it will follow the lane. The only thing it won't do is Assisted Driving Plus (aka TJA) and let you take your hands off the wheel.

Note, however, that in my experience it disengages more often on local roads. I will once again write that this is a driver assistance system and in no way should be considered automated driving. It's not. And never will be.
When my TJA wasn’t working prior to software update dealer tested it on local road. I told them you cannot verify TJA without driving on freeway and in a traffic jam.
