If you're talking on a cell phone (at 7 am, even) so intently that you cannot see what is in front of you and cannot remember your turn signal... Hang up, or park your car.
And don't park your car on or across the sidewalk. It's for pedestrians, not cars.
If you cannot see the area you're about to drive into, whether from sun, rain, snow, or dirty windshield, do NOT proceed. These are not excuses for a hitting cyclist or pedestrian.
I understand that the American driving public is unfamiliar with the purpose of a crosswalk, but they are not to be used for target practice. Especially in a parking lot.
