Robert Kamugisha had been desperate to sit his driving test. But the waiting list stretched for months, and every week without a licence meant more pressure - financially and personally. So when he was offered earlier test dates for a hefty fee, he took the risk. The 21-year-old criminology student from Croydon spent most of his savings - £726 - on three test slots, all bought through resellers who snap up appointments and sell them on at inflated prices. The actual cost to take a test is £62.
