I wasn't aware footman james covered modded cars? I would maybe watch what you say to them if they aren't in fact fully declared already.

Sounds to me like it was completely her fault. As you were on the roundabout and she was joining she should have given way. Even if you were in the wrong lane (i know you've said you weren't) she cant just assume you are going to take the first exit (or whatever) and not go straight through. Still her fault.

People see (or hear) a car and see a young man driving it and jump to all sorts of conclusions.
