In most series that use it, push-to-pass is a system that allows a driver to thumb a button on their steering wheel to gain a brief power boost in a bid to overtake the car in front. Simple enough, if somewhat artificial. But it's a term that takes on a different meaning in the British Touring Car Championship. Here, it's the colloquial term for an unsubtle and rough overtake: release the brakes early, nudge the driver ahead to force them off line and then claim the position.
The BTCC has long faced criticism for its 'door-banging' driving standards, not least because it is relied upon to set an example to the lesser championships which support it, including Ginetta Junior which caters for drivers as young as 14. 'What example are they setting?' the sceptics ask, and purists bemoan the tin-tops' perceived heavy-handedness.
But so far this year, the BTCC has enjoyed something of a soft reboot.
