Thanks for the tip! Their website does look interesting, but I need prescription multi-focals, so I chatted with them and they provided a few prescription glasses specialists in my area for me to work with.
Maui Jim do prescription varifocals. My optician recommended them, they’re great!

I saw a video that showed how in some models with idrive 7 you could adjust the rotatation of the HUD to deal with polarized sunglasses. They demonstrated the increased brightness through a polarized lense for a rotation if about 20 degrees.

Has anyone seen whether the i4 can rotate the HUD?
@gsbaker, the video below shows the settings related to the HUD at minute 5:30. The vehicle being demo'd is an iX but I'm sure the i4 is the same.

Thank you, MinhSATx. The image was brief but shows the rotation of HUD. Since HUD is projected from the curved screen and not into the dashboard, and the screens appear the same between models, we can suppose the I4 would get the same adjustment.

From the link below, at 0:53, it suggests using rotation to deal with polarized sunglasses.

The only thing is you might have to tilt the HUD significantly to see it clearly with polarized glasses. To see my wife’s Sonata Hybrid HUD, I really need to cock my head quite a bit. The i4’s HUD might wind up so crooked, it might look weird. I guess we’ll find out.

Looking at my laptop screen with polarized glasses, I find 30 degrees to be quite enough to see.

Let's hope the whole curved sceen is not a problem.

My m50 will be garaged most of the time.... currently working from home. Will get wife to take it to work a couple times per week...

  • will add aftermarket tint to the windows.
  • handwash when it needs it during the fair weather months...(I ordered the metallic white colour, so it should look clean longer...) my summer car is a 2001 Porsche Boxster S - black on black, and that needs washing more regularly
  • will likely bring it to the touchless car wash in the winter. I currently have a pass to use with our daily drivers...
  • still undecided on the ceramic coating vs spray ceramic vs synthetic waxes....
  • i will likely research undercoating for it, fluid film or something similiar.to protect it from road salt in the winter.

Hoping to keep it in good/excellent condition for 10-12yrs or so...

I'm learning to not assume , what might work in the ix , works in the i4. Their combined videos of both have been very misleading imo.
Maybe some brave soul, can compile a list of questions and submit it to Bjorn, so we can get some answers when it reviews it in more detail.

Good idea! I may not be very brave, nor practiced in creating shared google docs, but I have started a thread for emails that can later be compiled and forwarded to Bjorn and others.

Hi petee_c,

Have you come up with any information about undercoatings?

thanks

Hi XtBimmer,
Do you have an existing EV where you can try this experiment?
@gsbaker, experimentation is always good, but 1) I would not put any film on the camera for sure, it's visible in the middle top between the kidneys, and 2) it would boggle my mind that a plastic-only film would interfere with a radar-based sensor, electro-magnetism just does not work that way, BMW might be over cautious because some films do indeed have metal particles in there, e.g. the mirror tint films. However, I can see how a film would interfere with an ultrasonic sensor, these are normally identified on the car with a circular indentation, and most professionals would cut the film around it to allow the sensor to work properly but also because the film would "tent" around the sensor and look much less clean. You might want to clarify that with your installer.

Hi XtBimmer,

My bad , forgot about doing it
I'll get out there today and try on the sensors.
I can't see why it wouldn't impair it....yesterday I drove for a total of 5hrs ...halfway on my radar sensor, it had a sheet of ice on it and didn't disable it. Only times I've seen weather disable it, was in heavy wet snow, where it was completely covered.
It was-14c out , and I ended up needing a slight boost off my 12v, as at the charging station, the car completely died.
My bad though, what happened was, the charging station was acting up , with errors on the station and the Flo app couldn't see the station. Meanwhile as I thought it would have been a quick hookup, I had the heat going, and all lights were on, so it drained the 12v. I was prolly screwing around with app and unplugging and replugging it back in for almost 10mins.
Called CAA,,,buddy had a booster pack,,,hooked it up, power came back on,...let it sit for a bit , and good to go.
It was my mistake, too as I usually take a booster starter battery pack with me on long drives in the winter but I forgot it.
I went to another charged and got charged up for another 200kms and back home.
I don't think it's my 12v, I've had issues with that station before.
But I will check my 12v today, and then top it off with a charge while I experiment with those sensors.
.
The tow truck learnt alot about EVs though hehe
He didn't know they had 12v batteries.
It is recommended to have a battery pack like that if driving in very cold weather for a long period and that incident my fault letting it accidently discharge.

Good advice.

We must identify all the U sensors and cameras to the PPF installer.

Does PPF normally go over the grill and the headlights?

For what it's worth, I asked my local PPF installer about this issue. He took me on a tour of their shop and showed me their process and a few examples sitting in the shop. They do a lot of Teslas, and he noted that they have yet to run into an issue with PPF and any of the sensors on cars. I suppose there's always the chance to be the first, but that's a data point.

@teamzans, Tesla's don't use a lot of sensors, they only rely on their cameras. This is what an ultrasonic parking sensor looks like. The inner area of the circle is actually the surface of the sensor, if there is a film on it it will at least reduce the range of the sensor.

Seeing this may explain a question I had about individual paints. When I select individual paints, I get a warning about the lane assist option being dropped. I assumed it was a sensor thing, but thought it weird since the paint goes on the chassis first. But I can see how those sensors may have to be painted to match the standard colors. Go with an individual color, and they may not be able to match the paint on the sensor circles.

Just a guess.
