The Netherlands used to have loads of plug in hybrids. There were more than enough charging points. Most of those hybrids were owned by people where the company would pay to fill them up.
People were lazy and preferred filling them up with gas, most never used anything other than gas. That resulted in the government charging the tax benefit for hybrids.
The Netherlands has a huge amount of chargers. In e.g. Rotterdam there's at least a charging point every 50 meters.
