What? Every car can automatically change lanes, automatically merge into traffic, automatically exit to an off-ramp, automatically go around a round-about, etc? I think there may be a language barrier here because most cars/trucks I see on the road cannot automatically do any of these things.
Yes to all of those. Adaptive cruise control. Lane change assist. Auto braking. Automatic exits. This stuff has been standard for many years now, and every major brand is touching L2/L3 autonomy. Manufacturers just don't market it as "autopilot" or "fully self driving", because that's not what it is.
Sorry - just bought a new Toyota RAV-4; it does not have auto-lane change, the ability to auto merge onto the highway, the ability to auto-stop at the stop-light, etc.
It does have adaptive cruise control and the ability to stay inside the lines, but it absolutely will not automatically change lanes or exit off the freeway.
