Here's another thing I've seen recently and I can't figure it out at all --
Heading North East on highway 1 toward Keelung from Taipei, about 500m before the XiZhi toll booths, there's a pair of newly-installed gantries about 3 meters apart. The last two times I've driven under them, there was a flash - or more like two flashes very close together - something like a regular speed camera flash but a shade more blue-ish and much less bright. In daytime you might not even notice them, but this was nighttime. The first time it happened I may have been going over the speed limit, but the second time I was very careful to be well under (the posted speed is 90 right there) -- and it/they went off just the same. Plus in any case, the flash seemed to go off pretty much directly overhead, so I don't think they would have been able to see my license plates anyway.
I suppose I should somehow try to get over there in daylight and have a good look at the fuckers, but driving past them going the other way in daylight I can't see much of anything. Plus if they're those Komoto bastards, then why would they need two gantries for that??
So wtf? Is this some new system that's being tested? If so, what's it supposed to do? Why would anyone want a picture of the roof of my car? Is it to do with speed or what? Anyone have any ideas?
