2.4.4 Lane change assist less reliable on the right?

[OhmMyWatt]

Hi everyone! New owner of a 24 Touring with DDPro. I've been testing the lane change assist on highways and it works pretty well when changing lanes to the left (driver side). However, when trying to change lanes to the right, I found it way buggier and often just cancels the lane change with no reason. I've verified that there is a dotted line and no cars around when initiating the lane change, the car registers it, then the line suddenly becomes solid and it cancels the lane change. I don't see the error message for "Lane Change Assist Not Available" so the car clearly thinks it is possible. It happens reliably but it also did work once or twice. Was wondering if anyone else ran into lane change issues when going right (passenger side)?

Do you get a message that says 'keep hands on the wheel'? If so, nudge it. It's the same as the message that pops up in normal HA, but less obvious that you need to nudge it; it's a UX issue.

Until I figured that out, my LCA was cancelling randomly too.

I haven't seen that explicitly with the Lucid, but have seen that issue on another car. The worst time to give a message to hold the wheel would be when a person is making a lane change and is likely looking in the mirror, at the camera display, at the next lane, and anywhere but the message area on the dashboard. Also the idea that a person might not paying attention is a legitimate issue, but if a person is actively trying to change lanes, it's pretty clear that the person is likely paying attention. I don't imagine that many people will be signalling for a lane change when they are busy doing something aside from paying attention to their surroundings.

These are also the types of things that need an audio indicator option for when canceling, since a person isn't likely to be looking at the message.

I totally agree. Just a bad UX decision. I'm sure they'll fix it.

Not necessarily. People can hit it with their knee while distracted, or accidentally in some other way, or they might hit it and then their kid screams from the backseat... you never know.

Agreed completely.

I wouldn't say I never know. I sometimes know. I find it a bit farfetched to think that there are people accidentally hitting the turn signal lever with their knees, but you never...but you can't be sure that it never happens. I'm tempted to get into the car to see if I could even hit the lever with my knee if I tried...hang on...it was tough, but I managed. I had to open the door to do it though and I think that a lot of people would be hard pressed to do it on purpose.

Should change out the salk for wheel mounted buttons. That should keep accidental triggering from happening.

It would, unless you accidentally hit that part of the steering wheel with your nose.

While your response is cute, you’re intentionally missing the point. It is not absurd to think that people would hit the turn signal accidentally. There are a bunch of buttons on that side of the car (defrost, etc) and it’s not outlandish.

FFS, how many of us have accidentally hit our E-brakes instead of wiping the windshield?

These things happen.

I haven't, but I know that some cars have a windshield wiper control stalk on the left, and others have them on the right. Signal stalks are going to be on the left side in rhd countries and it's a harder mistake to make, but I'll admit to cleaning my windscreen in Australia and New Zealand when intending to signal. I don't think that it's likely that a person would inadvertently hold the signal lever in a position that would cause the car to think that a person wants to change lanes, but it's a moot point if the person isn't paying attention.

We seem to be going in circles here because even if I concede that a person might hit the signal stalk while not paying attention, the person would have to be paying attention to the binnacle to see the message. So it would be a limited case where a person isn't paying attention to the road or signal stalk, is paying attention to the message area of the screen while not watching the other lanes (due to indicating a lane change by mistake), not seeing the flashing indicator on the same screen from activating the signal, and then seeing a message indicating that the car isn't changing lanes when the person didn't expect it to. Since the warning would appear in that rather contrived situation when the person never intended to change lanes, all it might do is get people to think that they should be watching the screen while changing lanes instead of watching the road. And that's not sensible.

Guilty as charged and quite the experience I don’t want to repeat. Not a pleasant sound! When I got home I stood in the corner with dunce cap on.

You’re not alone, present company included. Lol

Not sure why there’s not a software check to disable e-brake switch while the car is moving.

Because sometimes you need the e-brake while the car is moving. Like if the brakes fail.

Did you have Beyonce playing.... "To the left, to the left"?

Probably me not following the thread closely.

My impression was the discussion was regarding accidentally hitting the silver button on the of the stock on the right hand side. I saw the term e-brake being used (though I normally would assume that to be shorthand for emergency brake, which would makes sense to apply in rare scenarios when car is in motion) ; however on the context it seemed the silver button being referenced is what put the vehicle in “park” which will make a nasty sound if you hit will in motion. That is the scenario I think could use a software check to avoid.

So is there an emergency brake that be applied while the car is in motion?

Found my own answer:

Emergency Use​

Pressing and holding the P (Park) button in an emergency decelerates the vehicle to a low speed using the service brakes, then applies the parking brake.

CAUTION: Driving the vehicle with the parking brake applied or repeated use of the parking brake to slow the vehicle may cause serious damage to the brake system.

So it’s not the same as putting it in park. Slick.
