If you're not looking, you can't guarantee that you would have caught the lights being reflected somewhere.

Nope, 50:50 is correct.

And the other reason is: as with most accidents, it's entirely possible for both drivers to come up with different explanations, both of which would fit the damage. With no witnesses and no admitted liability, it's always going to go equal shares.

And even if the overtaker is already well out, the fact he shouldn't be there at all in the first place still puts the majority of blame on him, in just the same way as someone would be if they had a head-on while driving the wrong way up a one-way street.
