Mounted under clear blisters on your car's roof would be either two or four of those pocket-pointer type lasers, on articulated swivels which would allow them to draw lines on their targets, like scanners at point-of-sale register scanners. These lasers would be mounted at an angle, and made to draw
horizontal lines on the adjacent vehicles, such that as a car comes closer to you (or you draw closer to a car), a horizontal line appears, low at first, but rising higher to indicate how much closer you are to the car you are approaching. The angle mount would be such that the line would be about 3 feet off the road at approximately 6-10 feet from the perimeter of the vehicle upon which it was mounted, at a fairly flat angle (with respect to the ground) so that useful information could be gathered up to 60-100' away, but at a sharp enough angle that the line motion would still be noticeable as you drew closer to a nearby vehicle.
Only two are needed if you're only concerned about highway traffic, but four could be useful in urban driving.
also would help with placing one's car in exactly the right spot in the garage.
Sonic detection (those old Polaroid Land Camera focus sensors) could be used to turn the lasers off when nothing is in range to draw lines upon.
The downward angling should be adequate to address eye-safety issues.

pretty much the same thing, except for maybe THE GUY BEHIND ME IS AN ARSEHOLE bit. [waugsqueke, Mar 12 2005]

Small child looking up : "Mummy, what are those red lights? Oh, never mind, they've gone now." |

Why can't you just glance over without the lasers? |

For viewing from the sides of one's vehicle, really, you can just glance over. But there are a number of studies indicating that human eyes are placed closely enough together that we have trouble accurately judging distances from objects that are moving directly towards/away from us. I think my suggestion would help provide easy-to-see indicator which is moving perpendicularly to that direct line of motion, and thus make it easier to perceive that we are getting too close to the car in front of us. |

Methinks these are baked. |

But nothing popped up on google. |

Baked in Canada.Nissan Murano has front mounted laser warning system for idiots who do'nt know they are following too close. |

Sorry No. If you do not know how to adapt your driving and keep a safe distance then this good idea will not benefit you. The fact that you have posted this is laudable but the fact is that people need to be educated in driving skills after they have passed their test.
This is just another thing to ignore! |

What about the laser being reflected off of the sideview mirrors of passing cars? Or being reflected off of puddles on the ground? Or for that matter, what happens when a laser hits some kind of reflector? or a really well polished deLorean |

Baked as [python] said, also at the rear to help parking. |

For close proximity detection you could use a laser (or light) passing through a diverging lens. As you get closer to an obstacle, the projected beam would get smaller and brighter. This would reduce the eye-safety issues. |

I DO like the idea, but yes, it's baked, so neutral I must remain. How about this - the rear sensor is tied in to a message display system so that when the person behind gets too close, it flashes an appropriate message such as "back off." |

Really, nobody had cryptocybers in mind back in 2005? |
