I don't quite understand the velocity part. How making a car in 25 sec is relevant to .2m/sec? The manufacturing line is much longer than 5 meters.Factory output = volume x density x velocity
Volumetrically - it's crazy low, 2-3% - lots of room for improvement
Velocity - Fast car production is .2m/second = a tortoise! Cars should be able to exit at walking speed!
Density - Ability to improve from 2%-3% to 20%-30%.
