SLEX radar vs speedometer reading

Do you know how we determined the accuracy of our speedometers in each everyone's car (different make). A simple method we always do. Drive and run in a convoy with only one takes the lead of the speed. The leader may run and maintain speed at 80kph and will not exceed. As we drove in convoy, ( in an expressway ) we glance and look at our speedometer points at that very same speed mark (80kph). It's fun, as we do it every year in a family field trip, or summer outing.

Let say 6 vehicles with different car makes, we all run at a speed of 80kph. All 5 vehicle match in each speedometer gauge, while the remaining 1, his gauge reads at 65kph while we are all running at the same speed. That means his speedometer gauge is out of specs calibration or faulty.

Or, you know, just compare it with a GPS reading from your smartphone...

yes, very convenient. tried it this afternoon.

Pwede rin. Why not.

If you're measuring heights, and one guy guesses he's five foot five, and you're all the same height... does that mean you really are all five foot five? (I've met guys shorter than me who claim to be five foot six... amusingly). You can't assume that because all the speedometers agree, they're correct. It can also mean they're off by the same amount. Again, almost all cars have speedometers that are exactly 5% fast.

Like jut says, only way to know for sure is to use a GPS-based measuring device, like a smartphone.

Tried waze and speedometer comparo earlier. Looks like 2-3 kph slower yung speedometer * speeds over 80-90kph. May lag lang ng konti yung sa waze (split second) reading, btw steady rpm and speed ko yun ginawa. (Obviously not an accurate measurement but a good basis din naman pala yung speedometer).

^ lest we forget, the discrepancy here is- 31 kph. and supposedly they got that thing only last April. 😟

Yes tama 31kph un dagdag haha take note un may ari din ng volvo sabi niya un nag test daw slex sa 24 oras news flat daw un radar na gamit tapos sa tv patrol pinakita vertical so anu radar ba talaga ginamit. Haha
Nabasa ko lang sa comment niya dun sa video ni james

Keep it at 90km para safe

[shok]

Keep it at 90km para safe

E di 121Kph din ang basa ng SLEX radar dun. Huli pa din.

Was he using the same car for the previous violations?

Sa video, makita na yung speedometer reading ng volvo is even higher than the Garmin GPS speed by +3 to 5 km/h to which it was compared. So actual speed ng driver is even less than 100kph in reality.

So WTF pano nangyari na overspeeding yung volvo by a whopping +31 kph? Nawala credibility ng SLEX, at engot talaga SLEX kung di nila ayusin itong problema na ito at the soonest possible time.

Pero malabo naman aminin ng SLEX publicly mali tao nila o equipment nila as like James Deakin commented, it opens SLEX to possible class action suit from people they wronged in the past. Tsk. tsk. Manigas na lang daw lahat ng gumagamit ng SLEX at nahuling "overspeeding."

Mukhang kelangan na bumili ng GPS / Dashcam, whatever, para lang makontra ganitong pangwawalanghiya at maprotektahan ang sarili. Dagdag gastos na naman sa mga motorista.

Sa isang interview na nakita ko, sabi niya he was caught 5x using 2 vehicles, both vehicles on cruise control even.

^^ may dashcam bang may gps speed na output? Or kelangan pang itutok sa gps mo yung dashcam para sa recording? Sorry noob question

Yung flat at vertical radars same ba yan sa speed gun na pinakita sa news clip ng ABS-CBN a few pages back na sabi ng SLEX eh acquired Brand New last April 2015?

Saw this one on the net:

All footage is stamped with time and location so you know exactly when and where events occurred. When reviewing footage on your computer, you’ll have a record of latitude, longitude, date, time, speed and direction of

Baka naman staying on passing lane dapat and violation and not overpaeeding

[Bin Diesel]

Ogag yang mga nanghuhuli sa SLEX dami bus na speeding di nila hinuhuli.

Mas malaki yata kurakot, este, fine sa overspeeding. :D Walang-wala kasi mga taga SLEX eh. :D

Pag bus, kawawa naman yung driver. Nagtatrabaho lang, arawan lang, mahirap lang.

Pag volvo / chedeng, mayaman naman yung driver. Yakang-Yaka mag luwal ng malaking halaga.
