Will you drive me anywhere I need to go or pay the difference between a self-driving car and a normal car if self-driving cars become available since I can't look one way let alone both ways? Proximity sensors aren't a good enough solution since as a blind individual I rely on hearing traffic patterns to determine when lights are red verses green. I'm sure you could create an electronic device for use by blind people what would interface with cars and traffic lights to make up for not hearing the noise but who will actually pay for the development and installation that would be required for such a device?
