Change lanes with auto driving and a car next to me?

Just watched a rollover with Porsche Cayman in traffic from a bad attempted lane change. Driver was using his phone during the lane change and clipped another car.

We know the W222 warns us when changing lanes. If car is in self driving mode and I initiate a lane change but another car is next to me, what happens? I’m sure lots of beeping. Is lane change canceled? Does car slow down or speed up?

In my experience, when using the auto lane change, it won’t make the change unless it sees a space to move into. I forget the exact behavior, but I have definitely tried it when a car was too close, and it didn’t lane change.

It should be like the spy movies where a spinning blade comes out of your wheel and knocks the other car off the road. Lane change complete.

It won't make the change if there is a car in the lane

That does not surprise me. I was just curious how it responds.

Lane guidance behavior changes when you turn on the blinker. Without a blinker... it will attempt to keep you in the lane (if it can see the lane stripes).... with a blinker... it will not keep you in the lane. The car assumes you have heard the warning and taken appropriate action.

That’s an option on the S63, us mere mortals can’t activate blades 🙁 Maybe BenzNinja can help? 🤣

How it behaves is explained in your owner's manual. If it accepts the lane change you get a green arrow and a message that the lane change is starting. If it can't immediately change lanes you'll get a gray arrow and the lane change will start once the lane is free. If it rejects the lane change, then the gray arrow fades away and you have to make a new lane change request. You can also bring up the driver assistance display in the instrument cluster where it shows this even more prominently with large green or gray arrows.

This may be accurate for the pre-refresh car. The post refresh car will change lanes automatically when in Distronic + and the turn signal is activated if the lane to the side is clear.

I should have worded my answer differently. What I was trying to say is even with lane guidance and the blinker on, the driver can still pull the car into another vehicle.

Well sure...with the blinker off it will let you affirmatively cross the lane line and run into another car

Why would you? Nobody is suggesting that you do.

Properly set mirrors don’t fail you. Nanny can. I like Nanny as a reminder but not as the authority.

You have seen the current Suburban? ad on the highway scene? No hands on the wheel at hwy speed? No way in hell! And to promote that is nothing short of negligence.

May as well get rid of driving age limits, too.

Happy to buy you a beer one day.

You still look at your mirrors. These things are just driving aids. I would never let the car change lanes without visually making sure that the lane was clear.

As for the SuperCruise on the suburban, I would absolutely take my hands off the wheel. I am still paying attention, and can put my hands back on the wheel. I take my hands off the wheel in my S Class, and SuperCruise is way more advanced. You realize that airplanes are flown by computer right? The pilots largely just sit there.

At some point, cars will drive themselves and yes they could lower the driving age.

I tested SuperCruise on a rental SUV, and I was impressed!!!!... Do you know if W223 highway assist offers the same level of precision as SuperCruise, or is Mbenz system exclusivity available on German and European roads only for now? I feel I missed a lot of Mbenz tech news in the past 4 years since I sold my former W222!

Distronic Plus is not as sophisticated as SuperCruise, the new system thats coming will be closer.

I needed a laugh, thanks.

When do you think mirrors will just be an option?

Planes and computers? Saving you from the IFR world, at 35,000’ the crew does not have to worry about wreckless pilots, coyotes or deer. And unlike a car, ATC has the plane from start to finish. Way safer in the air.

Thing about sensors vs eyeballs…..one has no clue as to your skill level.

There will be a time when cars have no mirrors, yes. We already have cars coming out with cameras instead of mirrors. With advanced systems like SuperCruise, the system knows where the car is and the roads are pre-mapped. Its only available on roads that are pre-mapped.

Like it or not, vehicle automation is not only coming...its here...and its going to be fine. I will never own a vehicle without at least the level of automated driving my S Class has, its a true game changer. So much less tiring on a long trip.

CyberTrucks is claimed to have a (removable) mirrors and would still arguable be legal to drive, but not legal to sell without mirrors

I am immersed in tech and have witnessed game changers beyond expectations. Tech has the unavoidable issue of selecting constants to manage the unknowns. Square peg round hole….but always improving. If automation produces a lazy driver….it’s back to the drawing board.

But, I would consider a camera/mirror combo. You should patent that.

Nothing to patent, they already exist.

Like I said, like it or not this tech is here and it’s only going to become more widespread. The result will be less and less of the drivers attention will be required to drive. That’s the whole point.

That will be a dangerous day and on the way, the plaintiff lawyers will have a field day.

Enough already. I need to calibrate my high tech tire gage.

Final question. Any guess as to when it will be safe for a driver to sleep and drive alone?

Can you share which tire gauge are you using?

It will be fine lol. Lots of cars running around with this tech too, where are all the accidents? Tesla has had accidents, but thats because they misrepresented their system as being "autopilot" and people don't have common sense.

When will it be safe to sleep when the car is driving? Its a ways off but the day will come.
