One thing that MIGHT help a bit is to actually have EV charging STATIONS, in the same way you have gas stations. Meaning, instead of simple parking stalls with a charger at one end, actually make it obvious you're entering a special area that is for EV charging (like driving into a gas station). A roof over the area, well lit, and actually looks like a gas station except without pumps. This will make it far more obvious what its for. I'm not suggesting most people park at EV charging stations accidentally, but having an obvious designated area where you feel like you're in the wrong place unless you have an EV will discourage ICEing. Further, if you drive an EV and aren't charging, you won't feel right being there either. You wouldn't park at a gas pump...
Which brings me to a small general rant that I think applies: There are simply too many "special" parking spaces at malls and offices nowadays. I think this contributes to people not caring as much and being sick and tired of finding a space only to find out it's "special". Look around, you'll see:
- Handicap parking only
- In-Store pickup only parking
- Drive-up food takeout only parking
- Resident only parking
- Staff/faculty only parking
- Doctor only parking
- Green car only parking
- EV Charging only parking
- Expectant mothers only parking
- Veteran only parking
- Employee of the month parking
- Parking for specific businesses only (e.g., coffee shop only, bank only)
- ...etc...
I have no issue with any of these specifically, but it all adds to the mind-numbing BS of the day, and I understand why some people get to the point where they just don't care. High fines don't stop people from parking in handicap spaces when they aren't handicapped - they never have.
