I see a parking lot next to the Otay crossing (one of three ports of entry (POE) in the San Diego–Tijuana metropolitan region) on https://www.google.com/maps/@32.5515469,-116.9389443,18.25z?hl=en:

There no business marked there, and Google street is not available (blue indicates Google street availability):
Since this is the nearest parking from the U.S. Customs and Border Protection's Otay Mesa Port of Entry and that Mexican authorities seem to sometimes give some headaches to non-Mexican citizens when driving in a car with a non-Mexican license plate, this draws my interest: what is this parking lot?
