Last weekend, Nick McKee from Newmarket took a drive to a Luton casino.
Before he'd even arrived, the night had got very expensive. In Luton, he took a wrong turn and drove on to the guided busway, going through a car trap in the process.
He couldn't leave the route for a mile and a half, and says the mistake caused hundreds of pounds of damage to his car.
Nick claims his sat nav took him onto the busway, which opened in September and cost £91 million.
He also says that same night, he spoke to a number of other drivers who'd just done the same thing.
However, Councillor Dave Taylor from Luton Borough Council told ITV News Anglia that the Council have checked the CCTV and that, as far as they can tell, what happened to Nick was a one off.
When it happened Nick thought he'd driven on to a train line.
A petrifying experience, he says he never wants to happen again.
