    Yup! This misconception is still very strong in the UK. I’ve seen people with modern vehicles with the A/C option, driving around in winter and on damp rainy days with foggy windows, not realising that the A/C could completely clear all this within a few moments.

    Indeed, many stupidly believe the A/C is only meant to be used in summery hot weather - and shockingly, won’t even use it then, as they don’t want to wear it out .

    Many seem completely unaware that NOT running the A/C on a regular basis is one of the primary cause of system failures.
    I’ve done my bit educating friends about the amazing dehumidifier capabilities of the A/C. Even on damp winter or rainy days, the A/C does an amazing job defogging ALL the windows, giving you much needed visibility.
    Turn up the temperature if it’s cold - the A/C will still dehumidify the interior of the vehicle and banish window / windscreen fogging if it becomes a danger.

    Or they have their system on recirc. Oh wait, that's their stupid Prius doing that.

    The design is hardly the primary reason. As noted in the article, the entire market has changed since the first Prius was introduced.

    Lol. If the climate control is in auto, it will turn on the A/C compressor in recirc. If you’re in recirc with the A/C compressor off, you did it yourself.

    At 15 degrees ambient (I assume that is 15F), there is very little humidity in the air, since the dewpoint cannot be above 15F. No conditioning of the air is required, it's already less humid than any air the air conditioner will produce since the air conditioner coils aren't 15 degrees at the surface. If you just open the vents and bring in the cold air (and add heat as required), then the windows will clear almost instantly.

    At least the Prius high-mid-dash placement is a closer angular distance to an external view that us already in the driver's external scan pattrn, than is the common low-behind-steering-wheel placement of many cars. As such, it is an improvement over them.

    While focal distance is irrelevant to most young folks -- as a teenager, my focus distance could adjust as fast as my eyes could change direction -- it becomes important for us older folks, where focus speed becomes significantly slower than direction change. The mid-dash placement is farther away then behind the steering wheel, thus requires less focus adjustment time when switching back and forth between external road scenes.

    That condition ends the instant humans enter the cabin and start breathing inside it. Mammal respiration expels a lot of water vapor, which then tends to condense on the inside of those 15F windows.

    Then, after the cabin air is warmed, it can hold a lot more uncondensed moisture. But the windows in contact with exterior air still stay cold, thus continue to be condensing surfaces.

    In some weather conditions, dry exterior air will clear the inside almost instantly. But those of us experiencing near-saturated outside air frequently find that the human-added moisture is enough to ensure continued inside condensation unless the AC is turned on. This is usually a greater issue at 35F than at 15F.

    Fair. It’s usually not an issue in the drier, colder climates. Moreso where the temp hovers around freezing and you’re dealing with wet snow or at least snow that one trudges into the cabin and melts and thus is a source of water vapour.

    People keep misinterpreting what I said. I said there is enough room ahead of the driver to move the existing display to the proper side without changing the the position of the display relative to the windshield. Leave the display above the steering wheel but in front of the driver. Heck, there's even room to move it further away. That's one DEEEP dashboard. That's what the last generation Civic kinda tried to do, except they had that weird dual dash thing going.

    I was specifically referring to the 15 degree condition. I suspect (but haven't confirmed) that at those temps the air conditioner will probably not even run - most cars have a low temperature shutoff for the A/C.

    I didn't catch that before. Farther forward, higher up (above the steering wheel), and straight ahead. You might say that I could get behind that if it really would fit. I agree completely. However, what we have is, in my opinion (and apparently that of a lot of people here on PC), the next best thing and it's so much better than traditional that I can't make myself fuss about it. Your idea would be the next logical step, though. (y)

    Edit to add: The hidden possible benefit of the present location is that it might help people get their eyes moving side to side and maybe eventually discover scanning so they don't get killed so often. Naw. I'm just dreamin'. :D

    BWAHAHA

    Edit to add that it would clearly require some engineering of the dash but that's what engineers are for.

    As a teenager, my focal distance was to wherever my girlfriend's sweater was...

    NiMH is more durable when kept to a narrow state of charge range. Honda wasn't sticking to that range, and that caused the issues.
    Li-ion's usable charge range for maximum life is twice that NiMH's. Honda had no problems with Li-ion equipped hybrids. Presumably they learned their lesson on pushing the battery too hard with NiMH.
    The only Li-ion plug in with issues of note is the Leaf, and that's because of inadequate cooling.

    With a mirror, the gen 2 Prius put the speedometer at the base of the windshield.

    The mirror idea is cool. I'll have to google that.

    As for NiMH and durability. They are really far more tolerant of abuse than Lithium. I have a hobby shop and we've had NiMH that are years old and abused as heck just merrily going along but Lithiums just freak out at the slightest hint of abuse. I'm sure that the charge profiles have improved but...not gonna be the guinea pig with Honda. Known too many people who were burned by the Civic hybrid.

    You are aware your Prime is Li-ion?

    We've had many Honda hybrids (every other year since way back) and the 2012 was the first using Li-ion. With loads of miles (still in the family as we've passed them on to the kids & grand kids) none ever had an issue with the battery. Honda did have a software update for the older NiMH hybrids, essentially detuning the IMA system so it uses assist less often to reduce the load and stress on the battery.

    One of the reasons we did not even consider earlier Prii was the lack of a Li-ion battery (and dear wife thought the Aztec like styling was beyond "fugly"). YMMV

    Of course. But I also know that Toyota has been super conservative in their batteries and basically isn't a worry for Gens 1-3 Prius and Highlander and Camry so I suspect the same level of reliability will occur in my Prime even with the different battery chemistry. And if I do need a new battery down the road I figure it will be a wash with the much reduced maintenance of the rest of the car's systems. I like to point out to hybrid shy people that a new transmission costs as much as a battery and they fail far more commonly. And my Prius doesn't have a transmission in the traditional sense.

    Obviously YMMV. I personally know 3 people who have had to replace the battery in their Civic Hybrid and I only know 4 people who ever owned one. Obviously not a representative sample but convincing for me. I know LOTS of people who have owned a Prius and besides groups like this I have never met anyone who had to replace a battery. I had a HyHy and it had 180k when I sold it with no indication that anything was going wrong with its battery either. But I'm a Toyota believer.

    Yeah, styling is certainly not the forte of the Prius. I like the Prime styling mostly, though the rear 1/4 is kinda wrong. But I also like Citroens so maybe my opinion is suspect.

    I can actually see my speed quicker in my Prime than I can my motorhome. My analog gauge on my motorhome is usually hiding the speed because of the steering wheel. I have to move my head around sometimes. Where in my Prime, it’s just a quick glance to the right and then back forward again.
