Well it is government run only so no axe to grind as it were. ...... snip ...... There is a clever "platform" that you drive the cars wheels onto and in turn it forces the individual wheel sideways and forwards/backwards to presumably show up knackered bushes. It is wierd inside the car while it does that a side at a time.
Sounds very similar to the LGV Testing Stations operated by VOSA where the commercials and buses get taken in the UK. I know them as 'shaker plates'.
Again, no axe to grind as they do not do repairs. 
I was thinking it sounds very similar to an SVA test which is done at the same VOSA stations as the goods vehicles. Seem to turn the gods vehicles round like they're on a production line, much quicker than a garage does a car MOT.
And with the price of car MOTs getting a bit silly these days, IMHO (can't blame the garages when it's 45 mins to an hour labour) I wish they did MOTs on the same basis.
