I’ve pulled into those ‘empty’ spaces myself. Even crossing into the other side of the road to do it. I see someone 25 feet back I must assume they are texting and don’t wish to be stuck behind them.
Oftentimes people might keep a 25 foot buffer so as to allow someone in or out of the driveway. They see someone trying to get on the access road from the shopping center, so they think they’re doing a kindness by letting them in.
In reality they are jerks by holding up the line and NOT allowing the 10-15 cars behind them to move on.
Jerks.
