I have just seen a post about EVs sales in the UK, compared to fossil fuel sales. The OP mentions "self charging" hybrids (using verbiage from article they are quoting from)!

There is no such thing as a self charging hybrid vehicle! If it was a self charging vehicle it would be a perpetual motion machine, if it converts another fuel to into electricity to run then it is a hybrid vehicle!

"Self charging" is just advertising bullsh*t
