That's not bad for one line. Most auto production final assembly lines make about one car a minute. Tesla Fremont is now running 7 days a week, 2 shifts, and talking about 3 shifts. That's usually considered overdoing it. Few auto plants run more than two shifts, and do maintenance on the third shift and Saturday. More than that, and quality suffers and the workers burn out. 5,000 cars a week per line is about right.
