Maybe it's just a pet peeve of mine, but the wording "Tesla Vehicle Charging Only" is ambiguous and not intimidating to drivers that might ICE spots. It sounds like a technical note that this device can't charge other makes of electric vehicles. Wording like what's on handicapped parking signs is more intimidating and clear to both drivers and cops. As a retired engineer that can't stop designing - I think signs should say "No Parking if not Charging" and every charger spot (Tesla or otherwise) should have a light that blinks "Charging" when current is flowing. Cops would follow a rule as simple as the handicapped rule and ticket any unattended vehicle if the light is off (even electric vehicles). Optionally, spots could also have a vehicle presence sensor that calls the cops (after a grace period) if the light is off.
