I doubt it. If you exclusively kill people outside the vehicle who are walking or riding bikes, you encourage people who don't have a car to hire the vehicle.

The only possible costs would be if they're made to pay a price in a court of law, which seems unlikely since the woman who was killed had a bike with her, and it's unknown if she was on the bike at the time, but she's been described as a pedestrian outside of a crosswalk. Clearly Arizona authorities just don't care about safety.
