Claim 0:
1. A blind spot warning system of a motor vehicle, with the motor vehicle having a longitudinal axis and a steering shaft that turns the motor vehicle relative to the longitudinal axis, the blind spot warning system comprising:
a steering angle sensor coupled to the steering shaft for generating a steering signal associated with a wheel angle in response to the steering shaft rotating;
a computer including at least one processor and a non-transitory computer readable storage medium storing instructions, such that the at least one processor is programmed to:
determine a blind spot region extending from a sideview mirror of the motor vehicle in response to the at least one processor receiving the steering signal from the steering angle sensor, with the blind spot region being spaced from a line of sight of a driver and having a current size and a current location that are based on the wheel angle, and the blind spot region having a forward boundary that is angularly spaced from the longitudinal axis by a first angle and a rear boundary that is angularly spaced from the forward boundary by a second angle; and
generate an actuation signal associated with the blind spot region; and

at least one light projector coupled to the at least one processor and projecting a visible light onto a roadway adjacent to the motor vehicle in response to the light projector receiving the actuation signal from the at least one processor, with the visible light indicating the current size and the current location of the blind spot region relative to the motor vehicle.
