James Deakin: "The truth about speed cameras down south"

[ghosthunter]

with this, im sure marami na bibili ng radar detector.

It depends what type of speed-gun is being used. There are two general types. Radar and Laser.

radar - NLEX, SCTEX, The Fort
laser - MMDA (commonwealth, macapagal), SLEX


Radar guns are relatively easy to detect even from a distance.

Laser guns are harder to detect because the beam is generally narrower (but some models have a wider beam for faster lock-on times). Lock-on times with lasers are generally under 3 seconds to even fractions of a second. This makes using laser detectors as a defense a problem. BUT there are always solutions.

ah. they're using laser pala in SLEX. i will try my radar/laser detector in SLEX tom. i've been reading, that if you're laser detector beeps, and you're speeding, it will already be too late to slow down. as compared to radar, you still have time to slow down.

for laser, i think laser jammer? tama ba? hehe

Yes, ironically while you cannot jam old style radar speedguns, there are laser jammers you can buy and install in your car. Effectiveness of laser jammers differs between brands. I am currently doing a bit of research into what is good and effective and still "affordable". So far it seems the "BLINDER" brand seems to be up there. They have a website based in Australia but you cannot directly order via the online store BUT contact them via email and they are more than willing to ship your order to the Philippines.

Only downside with laser jammers is that it is installed on the vehicle, so transferring it from vehicle to vehicle is out of the question. Also larger vehicles or vehicles with lots of chrome bits in front (like a large shiny bullbar) is a bigger laser target which require more laser jammer emitters to be effective.

In July 2011, ABS-CBN reported that MATES will strictly enforce speed limits: http://www.abs-cbnnews.com/nation/me...ex-speed-limit. There were reports of arrests and confiscated licenses. Details were also posted in another forum: http://www.bigbigcar.com/boards/defa...g=posts&t=4534. A few months after ABS-CBN broke the news, I went through the SLEX all the way to Calamba, in excess of 100kph and no enforcers were in sight. I assume this has been the case up until this article from James Deakin.

It's March 2012 and MATES is once again announcing that they will strictly enforce the speed limits. I went to Sta Rosa 2 weeks ago and true enough there was an enforcer under one of the flyovers pointing his speed gun at my car. Fortunately I was doing 110 but quickly managed to bring it down to 100. When I got to the Greenfield ABI exit, there were enforcers with 2-way radios and clipboards checking on the cars exiting. I was able to get through without incident. I believe my foray into 110kph was less than 1 min.

Moral lessons:
1. When the news comes out about speed limit enforcement, better believe it.
2. A few months after the news comes out, the "strictly enforced" speed limits will revert to being suggestions. Ningas kugon at its best.
3. Rules, regulations, exceptions on speed limits, overtaking, assigned lanes, etc. are nowhere to be found on the SLEX website, AFIK: http://mtdsltc.com/. If they're there, SLEX did a good job hiding them. So we have to rely on flyers that are easily discarded or news reports that are easily forgotten.

Yes, driving is more fun in the Philippines.

110 is not going to interest them... they want the big fish... 120 and over... preferably 140 km/h and up... as there's no reasonable excuse for claiming you didn't know how fast you were going at those speeds.

[Walter]

Speedometer readings of most cars are 5-10% faster than actual speed, so 110 kph might be only 100-105 kph actual speed.

Is this correct? how accurate is our speedomter? and whats factors will affect its accuracy?

Size of tires generally affects the accuracy especially if you have aftermarket wheels installed.

As said... tire size affects it. Manufacturers sell cars with different wheel options, and they're not always equivalent in size. Heck... even tires that have the exact same designation will sometimes have different sizes.

And stock speedometers are not calibrated. That is to say, the ECU knows exactly what speed your car is supposed to be going (within the margin of error created by the tire size issue), but the speedometer needle is not calibrated on most cars unless they're US highway patrol vehicles.

Most cars are within 5-10% of true speed (usually over). Some are worse... reading as much as 20% off at 100 km/h.

Parang may conspiracy ngayon sa SLEX,- approximately 80KPH lang ang takbo sa lahat ng lanes.... Mas delikado iyan, dahil kung may aantok-antok,- maraming sasakyan ang madadamay....
