Unless I'm on an expressway or an unobstructed three-lane highway, I usually avoid using the LTA in my 2024 PHEV.
When I'm commuting in the city, I disable it.
It remains passively operational, but you are in control of it.
Especially when combined with Adaptive Cruise Control, its pinpoint accuracy as I drove down the M1 from Doncaster for the first time was mind-blowing.
Unless I'm on a highway, I don't think it's smart enough to manage narrow or single-lane roads, much less heavy, congested traffic in London.
