Why would that be? If the source of light is moving at very near the
speed of light, the light that is emmited can still only travel at the
speed of light. Therefore the light moving away from you would do so at
1 s/decade (from your example). Now you say this is true for the
observer outside the car. Why would the occupant of the car (now very
massive, distorted and burned to a crisp due to increasing frequencies
(energy) of radiation that hits him/her) perceive the light from his
headlights as if he/she is standing still or traveling at
non-relativistic velocity.

You can answer by e-mail if you like as this doesn't really relate to
any of the newsgroups in the above list.

Thanks for any explanation,
