If you want to avoid a speeding fine then don't speed - simple. But it seems there may be another way to avoid getting snapped by a speed cameras.
Physics students at the University of Leicester have discovered that you can escape detection if you drive past a speed camera very, very fast. So fats that the camera does not see your number plate.
So what's the catch? Well it seems that for this trick to work, you'd need to be travelling at one sixth the speed of light, or 119 million miles per hour.
For those interested in the science bit, the calculations are based on the Doppler Effect which causes light to shift frequency. The faster the object travels, the greater the shift.
For the frequency of the yellow plate to shift enough to move outside the visible rage of the camera it would need to travel 53 million metres per second or 199 million mph.
Don't try this at home!

Shame. If you hadn't have put that then I would be setting up my experiment right now...

Not sure how you'd get up to speed with all those cobbles ;) _________________ Darren Griffin |

Didn't Fifth Gear actually carryout this challenge? |

I think they worked out the speed you had to be going to be past the marker lines - i.e. it couldn't take the 2nd photo as evidence.

I know nothing about the technology, but the speed suggested seems a bit high? I'm supposing that the camera is set to trigger at a certain speed, then take a second photograph at a set time after the first? Assume the time between the photos is 0.1 seconds, how far away do you have to be for the second photo not to be readable? I'm assuming something like 100 metres [makes calculation easier!]? Therefore the speed needs to be 1km/sec = 3,600kph.
But then, as I said, what do I know?? _________________ Mike R [aka Wyvern46]

The faster you travel the more time slows, so even if the camera caught you at this speed the speeding Notice would take 100 years in the post!

Yep, Top Gear did a test to find out how fast a car had to pass a speed camera before it would miss the vehicle in the second photo.
At 171 mph the camera just didn't respond at all _________________ 🔸🔸 Currently using TomTom GO 940 & Locus Map 🔸🔸 |

Jeez... you'd have to be really fat to obscure your number plates :-D _________________ 🔸🔸 Currently using TomTom GO 940 & Locus Map 🔸🔸 |

and 50 million meters/sec is closer to 119 million mph not 199 million mph so it may be worth a try! |

I've actually seen this happen, albeit with a forward facing camera. A year or so ago I was coming home along the A1 in France. I was doing an indicated 130kmh on my gps, when an exotic black sports car came past me literally as if I was standing still. The first flash of the camera occured after he'd gone past. To be honest, it frightened the life out of me!
