For one, the driver was turning right and only looked left -- I was still in front of him, and he never looked ahead; T-boned!
For the other, I pull up to a stoplight alongside a few cars, against the curb. There is only one lane for left/right/straight. No one had on turn signals. Light turns green, so myself and the first car go straight. Second car apparently wanted to turn right without signaling, and once again does not look to the right (looking left, maybe?). Cuts me off in their turn and I hit their right side door.
So yeah, can definitely confirm that people do not look when they are turning.
