Seeing Doc Wayne's post in the Co & Mo thread about police cruisers reminded me of something I recently noticed, and I thought I'd pass it along just as a heads-up. Maybe you folks have seen it before and knew about it, but it was my first time.
On the H1 Freeway in the Eastbound direction (in the Kaimuki area), under the Westbound off-ramp to Kapiolani Boulevard, there is a large pillar (for the off-ramp) and wedge-shaped space (under the off-ramp).
LE hides on the far side of the pillar in that space, and is not visible until you pass by and then it is too late. The unit then moves-into traffic, accelerating to follow the targeted vehice for a pull-over. In heavy traffic motorists seem unsure of just who is being pulled over, so traffic gets 'confused' for a bit until the targeted vehicle is singled-out.
People who frequent that section will be familiar; just a heads-up when heading home at night, or even during the day after work because of the sudden congestion and lane changes by other cars.
