There’s my answer. The LKA should always keep you on the road. It’s going to have to with driverless autonomous vehicles don’t you think? I almost became a statistic in a bad way and I’m dead serious about this !! I’m very apprehensive in using it again.

 

That's just not how GM's lane keep assist works today. For lane centering you need SuperCruise, and it won't deal with all construction scenarios. Personally I would never use SuperCruise in a lane-shifted construction zone - that is just asking for trouble.

 

I get it that I need to only use Super Cruise in pristine conditions. Makes sense. My misunderstanding for sure. It all happened in about 6 seconds and I took over the steering wheel before it even beeped because it was too close to the concrete wall and cars I was passing.

 

@REIDB, you really need to read the Owner's Manual. Everything both @hightech-guy and I posted are contained in the Owner's Manual.

From the section on Super Cruise:
Super Cruise should not be used in
complex or uncertain driving conditions,
including:
. Not in construction zones.
. Not when approaching or exiting toll
plazas.
. Not when approaching an intersection
that is controlled with a traffic light,
stop sign, or other traffic control
device.
. Not when lane markings are not
present or cannot be detected. For
example, there is too much glare,
weather conditions are poor, or lanes
are poorly marked.
. Not on slippery or icy roads.
. Not in adverse weather conditions,
including rain, sleet, fog, ice, or snow.
. Not on winding or hilly roads.
. Not for city driving.
. Not during heavy or emergency
braking.
. Not on surface streets.
. Not on a road shoulder, service drive,
or under an elevated freeway.
. Not when towing a trailer.
. Not in a highway exit lane.

And from LKA sections:
LKA may assist by gently turning
the steering wheel if the vehicle approaches
a detected lane marking. It may also provide
a Lane Departure Warning (LDW) alert if the
vehicle crosses a detected lane marking. This
system is not intended to keep the vehicle
centered in the lane.

The LKA system does not continuously
steer the vehicle. It may not keep the
vehicle in the lane or give a Lane
Departure Warning (LDW) alert, even if a
lane marking is detected.

Even with LKA and LDW, you must steer
the vehicle.

 

The odd thing I found about this situation is that the automatic forward collision braking system did not kick in to prevent you from running straight into the wall. You'd think that'd be the whole point of the auto braking features instead of what we have of it just jerking you around in reverse in the rain 🤣
