Piston Slap: Solving the Black Box Mystery

Hey Sajeev,

I have an auto parts question that I’ve been meaning to ask for a while but I keep forgetting about it. Back in February, going to my car after doing some shopping, I spotted a cute college woman acting strangely around her Volvo 850 sedan. She’d walk around it a couple feet then would look underneath it. I angled myself to take a peek and I saw her problem; there was a large black box being dragged next to the left front wheel. After exchanging pleasantries and a failed attempt to get the hood open (the car was an obvious salvage, the whole front end was visibly skewed to the right), I finally just reached under the car and popped the box out, muddy and snowy parking lot be damned. At the time I thought it was a windshield washer reservoir, as the hose that was holding it on was a similar size and had a similar fitting to a windshield washer line, but when I got home I realized it couldn’t be. There was no way of filling it or checking its level.

So what was it? My memory has faded on it a bit but it was made of jet black plastic, was roughly the size of a 124 count tissue box, had a hose at the top and two fittings at the base, there was a sponge inside of it and the whole thing came down from in front of the driver’s side axle line. It had some major road rash so all of the parts might not have been there. The thing that I really remember, though, that it was branded with the GM “Mark of Excellence”!

  • 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?
