it's a pressure sensor, not heat. else on hot day, the camera
will flash flash flash loh!
one thing about red light cams, u guys should be real careful when
approaching a traffic junction with cams. The light timings are a
bit different from 'normal'.
I kenna one where the amber -> red duration is less than 1
second. Basically u see the green turn amber, den immediately turn
red. That's one f ucked up timing.
When you pass the first white line while it is amber or green arrow
is flashing. you are safe. If you have not passed the first white
line while they turn amber or arrow is flashing. better jam break
siah... else is 12 pts and 200 bucks. fucking not worth it.
