Looks like there still won’t be any drive-through restaurants in San Luis Obispo. The city council decided to keep the ban on them that was introduced in the 70’s during the gas shortage. The reason back then was that it wasted gas if you sat in a drive-through line.
A local restaurant owner brought in a study that proved that today, it takes more gas to turn off your car and then restart it 5-6 minutes later than sitting in a drive-through line but the City Council decided to keep the ban. They think that forcing people out of their cars will make people enjoy the city more.
