This takes me about 5-10 minutes, since the sides don't have to have the exact same distance. You just have to be certain that the line is parallell. I know from my earlier measurements that I have an offset of 10 mm to the front rim from the rear rim, so I only add 10 mm to the number i get from the centre of the rear rim, when I read the scale in the centre of the front rim.
If I now want to double check I measure the distance between the laser units at the rear of the car, and compare that distance with the distance between the two laser lines I see on the wall in my garage.
But you have to be certain that the floor is level... Never forget...
Or you could check your car in one direction. Move the car 180 degrees and check it again.

I guess you could also find the center line of the car and either using a 3rd laser or just snapping a line on the floor mark that center line. Then measure your two outboard laser lines from that snap line to ensure they are parallel.
