ACLU Challenges Arrests For Headlight-Flashing To Warn Of Speed-Traps

There is more wacky traffic enforcement news coming out of Missouri this month than any other state. Last week, the Missouri attorney general began proceedings to shut down the ability of thirteen speed-trap-infested towns to generate excessive revenue from traffic tickets. Also last week, the cities of O’Fallon, Lake Saint Louis and St. Peters filed suit against St. Charles County saying its residents illegally voted for a ban on red light cameras. The suit actually admitted that the rationale was the potential loss of revenue rather than due to any safety concerns. Even better, the former mayor of St. Peters was convicted in 2006 of accepting cash kickbacks from a red light camera company. (For a truly astounding list of government officials who have been caught taking bribes from photo enforcement companies, go here.)

The big story is that the Missouri ACLU is going after the police department in the Kansas City suburb of Grain Valley for issuing tickets to motorists who tried to warn other drivers of speed-traps by flashing their headlights or high beams. My first thought was: wow, people really still do that?

The ACLU claims that such charges are unconstitutional based on the first amendment, saying that motorists are only expressing their right of free speech and their right to communicate with other drivers. They previously won an injunction against the City of Ellisville, Mo. banning the practice and will likely prevail here.

I say the practice is dying out. I drive a lot of miles, primarily on the West Coast, and cannot remember the last time I saw someone flash their lights to warn me of a speed-trap up ahead. During snowbird season here in Arizona, you do see tons of high beam flashing due to the elderly pulling their combination turn signal/high beam stalks when they signal a turn, so those do not count.

New technology may also be to blame for the demise. My Mercedes-Benz came equipped with Adaptive Highbeam Assist which does not allow for the flashing of the bright lights unless you change the settings in the COMAND system or turn off the automatic headlights. The widespread adoption of daytime running lights and automated headlights may means some drivers never even bothered to learn how to use their lights or high beam controls.

I also think that Generation Why has no idea what headlight flashing means and besides, who can text and flash their lights at the same time?

So do you flash your lights to warn of speed-traps or see others do it in your travels?

    Some flash lights if their is an accident ahead or if a bridge or road are out. This law is ridiculous and should be challenged.

    For an out of date practice, many here still practice it. I do it too.

  • Jalop1991 In a manner similar to PHEV being the correct answer, I declare RPVs to be the correct answer here.We're doing it with certain aircraft; why not with cars on the ground, using hardware and tools like Telsa's "FSD" or GM's "SuperCruise" as the base?Take the local Uber driver out of the car, and put him in a professional centralized environment from where he drives me around. The system and the individual car can have awareness as well as gates, but he's responsible for the driving.Put the tech into my car, and let me buy it as needed. I need someone else to drive me home; hit the button and voila, I've hired a driver for the moment. I don't want to drive 11 hours to my vacation spot; hire the remote pilot for that. When I get there, I have my car and he's still at his normal location, piloting cars for other people.The system would allow for driver rest period, like what's required for truckers, so I might end up with multiple people driving me to the coast. I don't care. And they don't have to be physically with me, therefore they can be way cheaper.Charge taxi-type per-mile rates. For long drives, offer per-trip rates. Offer subscriptions, including miles/hours. Whatever.(And for grins, dress the remote pilots all as Johnnie.)Start this out with big rigs. Take the trucker away from the long haul driving, and let him be there for emergencies and the short haul parts of the trip.And in a manner similar to PHEVs being discredited, I fully expect to be razzed for this brilliant idea (not unlike how Alan Kay wasn't recognized until many many years later for his Dynabook vision).
  • B-BodyBuick84 Not afraid of AV's as I highly doubt they will ever be %100 viable for our roads. Stop-and-go downtown city or rush hour highway traffic? I can see that, but otherwise there's simply too many variables. Bad weather conditions, faded road lines or markings, reflective surfaces with glare, etc. There's also the issue of cultural norms. About a decade ago there was actually an online test called 'The Morality Machine' one could do online where you were in control of an AV and choose what action to take when a crash was inevitable. I think something like 2.5 million people across the world participated? For example, do you hit and most likely kill the elderly couple strolling across the crosswalk or crash the vehicle into a cement barrier and almost certainly cause the death of the vehicle occupants? What if it's a parent and child? In N. America 98% of people choose to hit the elderly couple and save themselves while in Asia, the exact opposite happened where 98% choose to hit the parent and child. Why? Cultural differences. Asia puts a lot of emphasis on respecting their elderly while N. America has a culture of 'save/ protect the children'. Are these AV's going to respect that culture? Is a VW Jetta or Buick Envision AV going to have different programming depending on whether it's sold in Canada or Taiwan? how's that going to effect legislation and legal battles when a crash inevitibly does happen? These are the true barriers to mass AV adoption, and in the 10 years since that test came out, there has been zero answers or progress on this matter. So no, I'm not afraid of AV's simply because with the exception of a few specific situations, most avenues are going to prove to be a dead-end for automakers.
  • Mike Bradley Autonomous cars were developed in Silicon Valley. For new products there, the standard business plan is to put a barely-functioning product on the market right away and wait for the early-adopter customers to find the flaws. That's exactly what's happened. Detroit's plan is pretty much the opposite, but Detroit isn't developing this product. That's why dealers, for instance, haven't been trained in the cars.

  • FreedMike If Dodge were smart - and I don't think they are - they'd spend their money refreshing and reworking the Durango (which I think is entering model year 3,221), versus going down the same "stuff 'em full of motor and give 'em cool new paint options" path. That's the approach they used with the Charger and Challenger, and both those models are dead. The Durango is still a strong product in a strong market; why not keep it fresher?
