I saw an old thread on the site about the 11th gen windscreen demister and was going to reply, but didn't want to resurrect an old thread. So here we go, I hope this helps advise anyone interested in finding out how it performs, or doesn't.
My experience is that the windscreen demister is pretty poor, especially in cold weather. When you start the car and turn on the heater, the engine will start, as it needs to for warm air to be produced. If you press the windscreen demist button immediately, full air is directed at the windscreen, but as it's cold it does nothing, if the screen is frozen, it often compounds the issue, by actually misting up the inside of the window, especially if you use the recycled air button, which just seems to mist the screen. The better, but still not very effective option, is to leave the heater on auto, which doesn't start blowing air, until the engine is warm enough to produce warm air. Normally the system is intelligent enough to direct the air to the windscreen initially, but you may have to do it manually with the windscreen demist button once warm, if it's directing it elsewhere.
Ridiculously, the part of the windscreen that gets least air and always demists last, is the drivers side, directly in the drivers view, which is very frustrating. I've lost count of the number of times I've set off to work, not feeling particularly safe, as I lean over to the passenger side. As we all know, if you wipe the inside of the screen with a cloth, it ends up a mess and is so difficult to clean. It's just not worth it.
It appears the dash mounted blowers don't actually extend far enough over on the drivers side to clear the screen adequately in a reasonable time. I often find myself with my hand over the dash blower that's directed at drivers side window, trying to direct the air flow to the windscreen, to demist the bit the blower doesn't reach, the most important bit. It's that bad, I'm thinking of creating a plastic fin to redirect the air to the windscreen, crazy huh, thanks Honda.
You can walk away from the car with the engine started and leave it to warm up, you just get a minor external beeping noise to warm you. Of course it's at your own risk too, as the car can be driven off with no keys, I've tested it.
One last thing, having the heater on hurts fuel economy, really hurts it, as the engine will run most of the time. My 25 minute commute changes from 60mpg to 40mpg.
