We see this happened all the time. A car with its right turn signal on waiting on a street corner. With no oncoming traffic yet the driver still waited and waited and wait. By the time the driver finally decided to make the turn, traffic that was a few blocks away had arrived. Of course, everybody had to hit their brakes in order not to rear end this car.
The other extreme is drivers who come up to a stop sign, pause, look and proceed with the right turn regardless of traffic flow or speed of the oncoming traffic. The driver of this vehicle is one of them.
