Yes, sad and illogical as that sounds. The reason for this is that LTA functionality is seemingly something that needs to be integrated from scratch in a vehicle's engineering and design. In other words, I have yet to see a Toyota or Lexus vehicle in which LTA has been added in the middle of the model cycle. The 2019 Toyota Corolla Hatchback just happens to be all-new, and at that point LTA functionality was added.Is it true (for 2019) that the Toyota Corolla will have LTA (lane tracing assist), but the Lexus RX will not?
Apparently, yes. What I think are good sources of information are PDF documents linked from the Lexus USA consumer site that explain Lexus Safety System+ and Lexus Safety System+ 2.0Is LTA different from LKA (Lane Keeping Assist)?
To further add to the confusion, notice that my post above does NOT mention NX as one of the Lexus model lines with LKA. Rather, what your NX has (as well as IS, RC and previous-get ES) is Lane Departure Alert with Steering Assist (but without LKA). You are correct in that LDA (what you actually have on your NX) works without the Radar Cruise Control.It can be confusing. I have a 2019 NX and the LKA works without the radar cruise control on.
Correct. Think of it as an ascending stepladder that, depending on model, offers 4 levels of capability, as follows:Seems like LTA is a more advanced form of LKA.
