It's a really good idea and everyone hating on it probably doesn't understand it.Links 'n' stuff:Here's Prof. John Kelly's excellent demo of the eCVT (the me...
I drive a hybrid and it does not empty the battery and then fully recharge it, in fact, in the eight months I’ve driven it, as far as I can tell, the battery is yet to be fully charged.
It costs us about a quarter in fuel compared to the 15 year old car we replaced out of necessity.
We chose hybrid because the charging network is not up to the same density or level of competition as the petrol network and while the bulk of our travel is strictly local, we have family living 660 km apart, not to mention that despite having two power sources, it cost less than half of an electric vehicle which we could neither afford nor justify.
So far, the HEV is doing exactly what we asked of it and we’re happy with our choices.

If you’re driving your hybrid for such short distances that you aren’t using the entire battery capacity then you could do the same with an EV that has 4-5 times more battery capacity. In doing so you would no longer have to pay for maintaining and fixing two drive trains.
If you are driving distances of 660km then you are using the entire hybrid battery capacity as there are none that exists with battery range that big. There are only EVs with battery range that big.
I worked as an automotive technician for a couple decades and used hybrids were consistently traded in for having lost their battery capacity even within the time that the battery still had warranty coverage because manufacturers wrote their warranties to not cover “normal degradation” of hybrid batteries. They do this because of how fast hybrid batteries degrade compared to EV batteries just due to the design limitations I mentioned in my previous comment.
So you’ve seen how the car will almost immediately use any charge over 40% and charges when it dips below 30%? (Iirc, watched the video last night and don’t remember the exact numbers)
Yep, on a battery with 1.9kWh. For reference the smallest EV battery I know of is 20kWh. So it has 10% the capacity of the smallest EV battery which means it will cycle between charged and charging very often.
This battery will fully deplete when it is parked and this will lower the capacity
Because of how small it is, this battery will cycle multiple times per trip which will lower the capacity also
When the battery no longer holds enough charge to fulfill it’s purpose before the warranty has even expired the cost of replacement will not be covered because it is considered normal for them to fail so soon. So the owner will have to pay.

Did you actually watch the video?
Yes

The battery chemistry used in the car in the video is Nickel-Metal Hydride. Ni-MH batteries may have some defects, but what matters is that they discharge themselves. When the battery is not in use, it will slowly deplete its power. If the remaining battery time is long enough, the battery may be permanently damaged. A rough estimate of the depletion of NiMH batteries is that 20% of the battery power will be depleted within the first 24 hours after charging, and 10% will be depleted every 30 days thereafter.
It is expected that the charge/discharge cycle of a standard Ni-MH battery is 2000 times
Now consider the facts:
