As far as I can tell, it's for job creation. Still, their gas prices aren't any higher than in Washington.
I lived in Portland 30-ish years ago and there was a campaign to allow drivers to gas up their own cars. It went down to defeat 60-40 or some such. The commercials were incredibly stupid. One showed an old lady squirting gas all over herself and the wretchedly looking at the camera. But, clearly effective.
Is it really about job creation? I'm pretty sure those guys get minimum wage and there is very high turnover.
I assume there is no law regarding EVSEs though I could see the same people making ads showing some old lady electrocuting herself... Don't let this to happen to your sweet old grandma.
