Car appreciation... the aesthetics, the engineering, etc

I like fast cars- despite owning a Volvo.

But if I was in the jury and you started talking about your ceramic brake pads I'd assume you were speeding.

If she entered the roundabout when you were already on it (and you were not speeding) then simply stick to that:

• It was my right of way, as I was already on the roundabout
  
• She pulled onto the roundabout directly in front of me
  
• The direct cause of the collision was due to her contravening the accepted procedure for using a roundabout
  
  

If they ask about your brakes say that they were in good order- the car was MOT'd, and therefore deemed to have acceptable brakes.

Ignore what she is saying- if she pulled onto the roundabout in front of you and you were not speeding then it is her fault.

Keep it simple, stick to your guns.
