Onboard Speed Cameras - Is it Me?
It's not the first time I've seen video footage taken from traffic cars and thought this. Does anyone else look at the speed read out, compare it with the apparent speed difference to the other traffic and think, "There's no way the target bike / car is going that fast. You'd have to be crazy to believe they're doing 145 mph and the speed display is accurate."? Maybe it's just that I'm regularly overtaken by cars doing 200 mph, when I'm plodding along at an indicated 80.

I have noticed that as well ! A police interceptor ( think it was one of the Scoobies or an Impressa ) was chasing a Porsche at an indicated speed of well over a ton ( about 125mph or something ).
Well, the 40 ton artic they overtook must have been doing 110mph then ! So was the double decker bus ! Seemed odd at the time !

Speedo
After a recent inspection by the Swiss Traffic authorities on my 75 Tourer they found that there was a 10% difference between my Speedo and the actual speed allowed, in my favour. So when I thought I was doing 50KPH, I was actually only doing 45KPH. When you get up to 100KPH, your actually only doing 90KPH and so on. So in a 120KPH traffic zone I can actually do 135KPH without incurring a fine.

When you think you are doing 135kph, your true road speed is 120kph based on your information regarding your speedo. |

Subsequent EU regs require that a speedometer must never under read. So a speedometer that reads 100 mph when the car is travelling at 45 mph is perfectly legal (if otherwise useless!) |
