Erm.....a little at times, like when we were barrelling into corners with deathwish sheep in the road. She was worse to start with at the beginning of the faster bits, but I started to teach her how to "read corners" with vanishing points etc, so that rather than not knowing what was going on, she knew when I was going to accelerate or brake etc.
Seemed to work, as by the end of the day she was better...... still a little unused to the level of acceleration, but definitely better. She even said she was starting to like it!
But that was not me like a man possessed....... I would have been quicker if she had not been there......
