All those devices are available in every accessory shop in Taiwan. It’s open for sell and they take care of the installation.
I did not look at that, but I can imagine that it’s illegal, but speed is illegal too
The GPS is of course working very well, no doubt about that. I as I mentioned before, the laser detector does work
I tried to do the same for a while until one day I went to Kaohsiung and had to face 3 laser pointing at me !!! I just can’t keep the 90 KM/H on a highway.
Most of my colleagues are using those cheap detectors, but it bips so many times that they just don’t listen to them anymore. That’s why most of them still got tickets.
So far so good for me, and the experience I did with the cop pointing a laser at me and disapointingly lower down the gun when I passed-by shows the result.
The problem with speed limits is that, it does not consider the time (pick time, night, day), and conditions (dry, wet, busy, empty) and car condition (new car, old car, with or without ABS etc…), sure it would not be possible to have limits for all those cases but taking the worst case to set limits is not fair for the others.
What about scooters? It looks like they never get cought when passing a speed trap !
