Forty years later, German Tugas, a 42-year-old Uber driver, got to know it for another reason: Its parking lot was a safe spot to sleep in his car. Most weeknights, Tugas drives over 70 hours a week in San Francisco, where the work is steadier and fares are higher than in his hometown, Sacramento. So every Monday morning, Tugas leaves at 4 a.m., says goodbye to his wife and four daughters, drives 90 miles to the city, and lugs around passengers until he earns $300 or gets too tired to keep going. (Most days he nets $230 after expenses like gas.) Then, he and at least a half dozen other Uber drivers gathered in the Social Safeway parking lot to sleep in their cars before another long day of driving.
