Lane assist is unimpressive, requirements, technology and capability wise. Also, a fourteen year old can do it from the passenger seat.

(Also they don't really work reliably: try using lane assist with roadworks markings and watch your car veer off into the barricades. Or just too-unclear-for-machine—but-blatantly-obvious-for-human markings, like the dead Tesla driver from a few weeks ago encountered. Even a fourteen year old doesn't make that sort of mistake.)
