Illegal use of the HOV lane is also heinous in rush hour, since that one selfish person is holding up hundreds of people in carpools and buses. Enforcement should've been automated long ago.
I’m curious how you think it could best be automated. Even with the toll lanes on 405 and 167, it’s entirely honor-system when it comes to drivers following HOV rules, and the 405 has cameras. Toll cameras, of course, but even that system is far from fool-proof, with the only real advantage being able to toll everyone without a toll tag.
Some examples of low HOV compliance I can think of:
* Northbound 1st Ave So. Bridge; I would guess that 75-85 percent of the cars are single occupancy.
* On-ramp to southbound 405 from Maple Valley Hwy; the left lane is HOV 24/7 (unlike the 405’s HOV lane) but the ramp meter that it bypasses is almost never active, even during rush hour. Drivers seem to routinely use both lanes when the meter isn’t active (including myself once or twice, to be honest).
* Non of the “3+“ lanes (520, 405 ETL) seem to be observed. Traffic seems to be largely carpool, but 2 passengers seems like a lot of the traffic.
