OK how about...
- an object in your lane - the vehicle ahead goes over it or swerves to avoid it (think tyre, bumper, load from lorry)
- the vehicle ahead has a head-on with one that's crossed the central reservation or simply going the wrong way
- and most commonly, you're following a high-sided van that swerves at the last minute to reveal a stationery vehicle. (this happened to me )
Even someone suddenly braking hard is an issue with a 2 second gap...remember the 0.7 'thinking time' - delay it a little bit and you're be in the back of them before you've even touched your brakes. It all happens so fast and that's what catches people out every day on the motorway. I bet 90% of the collisions on motorways just wouldn't happen if the everyone stuck to 2 secs or more.
