Woman kept the paperwork proving she'd returned the car.
Paperwork?
I've had occasion to rent cars while traveling various times, and I don't recall ever receiving "proof of return" paperwork when I took one back.
Not even a receipt? These days there's usually a guy that checks the car and prints it out so you have something for your expense report.
You get that when you check the car out.

No, I get it when I return it. Granted, it's been a couple of years at this point, but there's always a guy with a mobile receipt printer. I mean, yeah, you get the estimate with the paperwork up front, of course.
-
@boomzilla Technically, in a fully-insured, gas-included, time-limited package, the up-front price is final. Which is why the final receipt can be printed up-front.
If you were to return the vehicle late, of course, they would charge extra fees. And then you'd get another receipt.
-
@acrow yeah, I figured some pendant would show up to tell me about that. I generally don't buy the gas up front. Their prices are always horrendous on that.

Compare to gas prices today. They weren't wrong, just early.

Oh, I'm not telling you about it. Just mentioning it for the audience. That's the problem with public speaking and movies; you have to mention the bloody obvious just to forestall the question. One post instead of two for the question and answer.

Any human driver can do stupid things on the road, but when you really wanna fuck up, take latest internet connected technology. Like Robotaxis.

Looks like someone used asphalt for colder climates, and it got all melted to hell. We get that on some summer days here because our asphalt needs to cover a stupid wide temperature span, and sometimes summers get too hot for it. Though, usually this just means it'll turn to a 0 friction surface, not get rolled up by tires but if traffic moved slow enough I guess that'd happen.
-
@boomzilla DC? I'm sure it was melted by too much hot air from too many bloviating politicians.

I love the random unrelated callout at the end:At least five people were hurt on DC-295 nearly a year ago, when a truck struck a pedestrian bridge and it crashed down onto the roadway.

I didn't find an English version, so a google translate:

Destroying the car this extensively does not sound easy.
you can't even drive 100 km/h there, what a tank stadium it is.
That's an interesting mental image. I assume it's a literal translation of an idiomatic expression.

I don't know where Google Translate got the idea to translate “tankodrom” as “tank stadium” when the word “tankodrome” (or “tankdrome”) does exist in English. And yes, it is a common idiom around here to call a bad road with a lot of potholes a “tankodrome”.

@Bulb said in Driving Anti-Patterns - Necro Edition:

TIL. Wiktionary says it's obsolete military jargon. I'd never heard the word before.
-
@HardwareGeek It does not mention how it would be called in a non-obsolete way though.

@Bulb In case of a road in Finland, I think I've heard "Emmental" and "lunar" used as adjectives.

@Bulb said in Driving Anti-Patterns - Necro Edition:

I personally call these "hen coops" because a pothole in French is a "hen's nest." But despite my best efforts it's not (yet) a common idiom.

Someone else tried this yesterday, but failed to destroy their car so comprehensively.
(I'm joking about it because amazingly given the whole sequence he came out of it unscathed, safety of these cars is impressive)

@Zerosquare Why did it fail so fast, though? Shouldn't it be able to maintain flight with one prop out of 8 damaged? Or did the flying fuck just fuck up the controls?
-
@Applied-Mediocrity The flying fuck fucked up the controls. After the ball was pushed away, he tried to back away to see what was up, and then repeatedly overcorrected to the point that the (fixed pitch) props had a useless angle of attack.

It's a Facebook link but it's a pretty firm reminder of why you shouldn't use tow hitches for things they're not meant for.

TL;DW: They did a whole bunch of things wrong.
- They didn't attempt to dig the truck out. Even if that wasn't effective to get the truck out (and my guess from that picture is that it probably wouldn't be), it would at least reduce the amount of force required to pull it out.
- They attempted a kinetic recovery with the wrong kind of strap. Kinetic recoveries are done with a rope or strap that is designed to stretch. The kinetic energy of the pulling vehicle is stored in the rope/strap as it stretches, which applies a huge amount of force to the stuck vehicle. If this is done using a rope/strap that doesn't stretch, that force is applied to the system (rope/strap, pulling vehicle, and stuck vehicle) in a sudden, violent impact, and the probability of something breaking is much higher than if it's done properly.
- They attempted this using a hitch in which the force applied by the rope/strap was not in line with the force applied by the receiver, creating a bending moment in the hitch. When this bending moment was applied suddenly, it exceeded the strength of the hitch and it broke. The recoil caused the broken hitch to fly back and strike the stuck vehicle.
- The kinetic recovery should not have been attempted until all other methods had failed. It is the method of last resort, but as noted above, there was no attempt to dig or improve traction, nor does there appear to have been any attempt to winch it out, all of which should have been attempted before trying a kinetic recovery.
-
@HardwareGeek Yeah, judging from the level of mud around the wheels, this seems to be on par with the attempt to pull a steel pole out of concrete.
-
@Rhywden I've seen some videos where they did kinetic recovery of what didn't look much better. But with a proper kinetic recovery rope. That was the key mistake. Yanking must only be done with a rope designed to handle it.
-
@HardwareGeek said in Driving Anti-Patterns - Necro Edition:
it exceeded the strength of the hitch and it broke.
Something I've noticed across various videos and pictures is that not all hitches are equal...
Around here, I don't think I've ever really seen anything but "swan's neck" hitches, like these:
These seem to always be made of a single piece of metal (except maybe the ball itself?), which means they don't have the failure point along weld lines that's discussed in the video:
(red arrows are my own high-quality editing)Now obviously the rest of the discussion is still valid and even with a more robust hitch not using the right attachment point or strap is a bad idea and maybe the hitch would still have failed etc. but it also seems to me that, as I said, not all hitches are equal.
-
Last Saturday, I went on a bicycle tour. The perfectly asphalted cycleway went down at a nice slope, and I let the cycle run. Doing some 40 km/h, something hit my right upper arm, bounced off, hit my left upper leg, then got stuck just above the knee.
So I stopped, and let that beast walk onto a finger which I pointed at it. It walked very groggy. I took a closer look at it, and it decided to take off. Its flying capabilities were similar to a 737 Max, and it fell into the grass of the nearby meadow. Took off again, then landed on its back on the asphalt. Took off again, etc...
I looked at it: a hornet.
Well, I hope next time it will remember the lesson and accept the fact that a cyclist has the right of way, even when the hornet crosses the way from the right.

Receiver hitches aren't common in Europe like they are in the US.

Regardless of the hitch style though, recovering from the towball is a bad idea because there's a risk the towball itself can come off and that's going to kill if it hits someone.

Yeah but seeing videos like these, I'm quite glad of that. All those "US-style" hitches look to me like something welded together by a redneck in a trailer park. I'm sure most are OK, and especially when used for normal towing and not kinetic recovery, but I would still be if I had one on my car.

Obviously, yes, but you're just repeating what I (and the video, and everyone who posted here) said.

@acrow said in Driving Anti-Patterns - Necro Edition:
@BernieTheBernie I'm reminded of:
any sail ship, even a tiny dinghy, has always right of way on any non-sail powered ship. Or at least I was told when I learnt sailing.
Of course, I was also immediately taught that having a right doesn't mean that exercising it is a good idea (also that you might still have right of way, but you likely have much more manoeuvrability than they do and they might not be able to give you way even if they want to!), and that such ships have countless ways of making your life a nightmare while still giving you way.
Basically "don't be a dick." ()

sensor might not be working faultlessly anymore.
On the other hand, it may not have worked well before that impact, either: how else would it fail to attack a cyclist?

@Applied-Mediocrity Bee. Hornet. Same difference when you hit them.
For some reason, I can't find any videos of a bug hitting a windshield. So here's some birds instead. ETA: Not meant to be funny. They just happen to be what Google gave me when I tried to find a video of a bug hitting a windshield. Sort of fits the thread so I posted them.

I guess I should give towers more respect. I always figured their training was about 2 minutes.
