How accurate are our speedo meters?

How accurate are our speedo meters? When I am travelling on the expressway and my speedo reads 90km/h, but I still see cars overtaking me left right center... Maybe my speedo is spoilt...

dun think so.

 

unless u have changed ur rims/tyres so much so tt it affects ur speedo.

 

maybe all of them are indeed travelling faster than u. no cause for alarm.

If you're driving the Optra, yes, our speedo is slightly overstated.

 

Speedo 90km/h = actual 80+km/h.

If u kena caught by TP for speeding , they will tell u how accurate is ur speedo vs their laser...

By default the speedo is 2-3kph below actual.

 

My analog speedo reads 90 on the dot while digital is 87-88kph.

 

Don't take my word seriously and do 93 thinking your doing 90kph actual and end up being fined.

 

But if your being sarcastic than yah ... there are outstanding citizens who would like to contribute to Singapore's Economy. I'm one of them

Well ... you know there are morons around who would rather fine people for 1 kph above limit because its easier than jailing racers who would like to contribute to Genie's Organ donation scheme.

[Jkl78]

maybe u should do a similar observation when u r approaching those speed camera along the expressway,

 

if ur car is close to the speed limit and cars are still overtaking u left, right ,centre, u r pretty sure ur speedo is faulty..

Speedometers are designed to indicate 5 to 10% more of the actual reading for safety reasons.

According my GPSR Garmin Quest, which measure the vehicle speed, when I am travelling at 90 kmph, actual speed is about 85 to 86 kmph. This would mean that the vehicle have a 6% up-play of the actual speed.

 

When I flat out my Optra on the highway, the meter reached a max of 190 kmph but my GPSR showed max vehicle speed clocked at 180 kmph

 

So you problem of travelling at 90 kmph and people are still overtaking you ? Have it occurred to you that they are speeding above the 90 kmph limit themselves ?
