Same here.
I'm blooming sick of adult cyclists on the pavements - I've been knocked down once and narrowly missed being struck by others - one time when I was very heavily pregnant. I've had to jump out of the way before to avoid a cyclist on the pavement (though to be fair they have all been young/ middle-aged blokes - I've never personally encountered a female cyclist)
If you are an adult, and you aren't able to ride on the road, then don't ride a bike.
It was dreadful that the cyclist died, but it could just as easily have been a pedestrian who was forced into the road and struck by a car.
I agree that continuing to do her shopping when she must have been aware that a dreadful accident had happened was callous and uncaring, but being callous and uncaring isn't illegal.
I'm sure that this heartlessness would have affected her sentence, after she was convicted.
