They would certainly have come off worst .
If a head on collision was going to be unavoidable, I’d be looking at options like going into a field ... any escape route is preferable.
In my crash I had my near side wheels on the grass verge once I’d braked off as much speed as I could on the tarmac , but still couldn’t completely avoid the car , perhaps going through the hedge and into the field might have been better , but with only seconds to think one largely acts on instinct ; in my case brake hard then swerve left at the last moment , whilst still trying to retain some control .
I couldn't risk the verge as I was still braking at max when he passed me. God knows what would have happened if I'd tried that.
