Harry,

I work at the a car factory and we can 4 wheel align a car in under 45
seconds with our ultrasonic alignment equipment. We have found the
ultrasonic system is more reliable than a laser system in high humidity and
heat environments such as a non air conditioned assembly plant. The laser
wavelength tends to become distorted in high heat humidity conditions. Which
causes the cameras to have difficulty reading the tire location properly.


I've heard that you can get a brand new car and the alignment will be
off, because they don't align every car that comes off the assembly
line. Is that true where you work?
