*How was this not "careless driving"*?

Abdelyekini Olafusi was found guilty of careless driving after he ran
down the woman in Clerkenwell.

Olafusi clipped the back of the 41-year-old cyclist’s wheel when he
turned right at traffic lights on Gray's Inn Road on May 27.

The cyclist, an Italian woman, fell off her bike to the ground but
Olafusi did not stop and continued to drive over her.
