I've been parking like that for about 50 years. Only time anything was an issue was once in downtown Birmingham, I parked at the courthouse like that.
The policeman saw me, swung around. Noticed the car ( on the right as pictured above) was over the line in the back of his vehicle and gave him(her?) a parking ticket.
He just looked at me and smiled. I went on about my business and still didn't feed the meter.
