Why you should always assume the driver has not seen you

I have to agree with this. There are laws, and there is common sense.

I used to row on the Thames, with big boats coming past. As a non-motor boat I had certain rights of way, but I always remember what my coach said to me "Being right doesn't help if you are dead, stay the fuck away from other boats".

And that's the same principle I apply to cycling.

Another numpty.
