BlueCruise and Rain

[Mach-Lee]

I’m actually surprised that the program would allow you to use BC in the rain. Using any kind of cruise control in rainy conditions is inherently dangerous because of wheel spin. Granted some cars nowadays can correct for wheel spin it just makes sense to drive yourself in the rain.
Insurance companies love to deny claims for people that use driving assists in inclement weather conditions.

The stability control and ABS can compensate for wheel spin and hydroplaning to the extent that is possible via available grip. Torque will be instantly cut if wheel spin is detected (it won’t keep the throttle in and spin wheels like old cars). It is a modern advanced system designed to be safe, and will automatically cut out if conditions are too adverse.

BlueCruise works just fine in light to moderate rain, as always you should be paying attention and ready to take over at any moment. I personally only disconnect BlueCruise in the heaviest rainstorms (red on radar) where there is significant hydroplaning risk (if it hadn’t already disabled itself). And because you want to slow down in heavy rain anyways. It should be based on driver judgement, but I would not make the statement that BlueCruise is unsafe to use in any rain—only with heavy rain.

I’ve also used BlueCruise in snow, but use is limited because the lines typically get covered fairly quickly during a storm. ABS will be automatically used to slow down or stop if the wheels lose grip, even if your foot isn’t on the brake pedal. I have a lot of experience using it, know its limitations, and when to take over.

Since BlueCruise doesn't work "in towns", you're good...

But lane assist will.

BC like cruise control and other assisted driving options are usually suggested to not be used in inclement weather like heavy rain and snow. You want to be in control.

Is that new? I don’t see that in my 2021 manual.

Page 242 says go to Whisper mode. I think it mentions BC or 1-pedal in a different section

I drove Friday night for the first time in the rain. handsfree disengaged when the rain was heavy, came back when it lightened up. adaptive cruse control was good.

Page 242 in my manual is about “Pre-Collision Assist.”

This is the only warning I have about 1PD (page 224):

Lane Keeping stays active a lot longer than Hands Free on most of my rainy-day trips.

I don’t disagree with you. BC and the camera/radar system do an amazing job. But the actual road conditions are what affect the braking. The big difference for my area is So Cal streets and freeways are horrible when it comes to water drainage and significant pooling of water can happen if we get 1/2” of rain in a short period of time.

Also, because of the amount of vehicles on the road, our roads are very oily and slippery at the begging of a rain. Even a light drizzle significantly reduces traction on the roads. The first few hours of any rain causes the most accidents because of the loss of traction. So if you are in So Cal and the weather goes south, take over and drive the Mach-e.

Maybe it’s the 2022 manual.

Your original post was about one pedal drive. This is irrelevant.

 

[Mr. Toejam]

Your original post was about one pedal drive. This is irrelevant.

I mentioned this because BC and 1-pedal will react the same way if the vehicle starts to hydroplane during braking. BC will be even worse because the driver will not be 100% engaged with the vehicle and might disengage.

So not irrelevant. Just additional info.

It works as it should. Which is why I did not renew the subscription. In heavy rain, sleet or snow Blue Cruise does not work and reverts back to the driver.

This obviously for safety and I have no issues with this.

BC expects you to be situationally aware at all times. It relieves you from the chores of driving, not from the oversight. Most of us find that very relaxing.
