I cannot believe what I am reading in your column about two-yearly MOTs. My son is in the business and takes in many cars and vans for MOTs. He continually sees vehicles that are downright dangerous. Two of the biggest culprits are tyres with little or no tread. It is nothing for him to have to fit four new tyres. The second is brake pads very often worn right down. He tells me that broken springs are also high on the list. He even found one on my car that I knew nothing about. Two-year testing will put many testing stations out of business.
