A singular brake engaging isn't really failsafe on a train. If a wagon in the middle of a train at speed has its brakes suddenly engaged the wagons behind it will crash into it, fly through the air into neighboring trains and houses.

Failsafe would be when all the breaks on the train engage at a safe breaking power, which is the behavior on controller failure but this is unrealistic to implement for power failure.

Fair enough but I think most trains have brake continuity or something similar - if a brake comes on somewhere they come on everywhere. Obviously a bit of a fucker if you do have a brake failure as its not immediately obvious where the problem is.

I'm no engineer but a potential problem I see with using a powerful enough spring to provide the needed braking power is having enough pressure in the system to overcome it. Google tells me that truck brakes operate at about 50% to 100% higher pressure than freight train brakes.

It's late and I'm tired but I think there may be other design implications from the pressure in the pipe providing the anti-braking force and not just "enough pressure to cause the valves to operate when it drops", but I can't think of any examples of what these might be, maybe it's nothing.

Another minor concern is that maintenance would be a pain - if you remove the pressure from a Westinghouse system you only have to fight the relatively weak return spring to (dis)assemble the brakes.

On top of the blindness, it sounds like he's mentally handicapped. I wouldn't want him operating anything with an engine in it, let alone a vehicle.

And his boyfriend keeps encouraging him to keep driving, even though it's completely obvious that he's unfit for the task. If your partner is such a terrible driver that they're going to kill themselves or someone else if they don't stop, the caring thing to do is to convince them to give it up, not keep telling them that they're gonna get right it one of these days!

One really poignant episode of the show had a woman who had been nominated by her husband as the worst driver. When she was doing the driving training with the instructors she was anxious but generally did pretty well -- but when she did the tests with her husband in the passenger seat, she kept failing. The cameras showed that he was a huge rear end in a top hat and was just yelling and berating her constantly and grabbing the wheel out of her hands and poo poo. The show cut together all of the insults that he yelled at his wife and put them on a CD, and the host took him for a drive to listen to himself:

I've watched a couple of the last seasons of CWD on youtube, and I'm equal parts horrified and entertained. Many of these people have such severe mental issues or are so foundationally bad human beings that if you fixed everything about their driving 100% and they never touched a steering wheel again, they would still be just as much a danger to themselves and others. That kid with the Justin Bieber haircut and arm in a cast belongs in a mental institution, not out in public.

There was one guy on CWD, Scott, who got kicked off the show partway through because he was such an aggressive rear end in a top hat that his roommate got fed up and canceled his insurance, which prevented him from legally driving. He would weave in and out of traffic at 90 MPH for fun and had owned over 60 cars because of all the crashes he had. He got arrested for speeding again in 2015 for going over 100 MPH with a suspended license and unregistered vehicle.

And then on another season Angelica got removed from the show and sent to rehab after she had an emotional breakdown basically any time she had even minor stress and it turned out that she had severe untreated mental illness that she tried to self-medicate with alcohol and stolen prescription drugs. Guess who got a DUI arrest a few years later?

quote:

A Calgary man who police say was caught speeding along Stoney Trail early Sunday morning says he is "innocent until proven guilty."

Police say Scott Schurink, who was once featured on the show Canada's Worst Driver, was allegedly driving 176 km/h in a 100 km/h zone. He now faces several other charges including driving with a suspended licence and operating an unregistered vehicle.

This was after the show aired.

He's still not as bad as the guy from Innisfail who had like 5 DUIs and just couldn't stop drinking and driving.

I don't understand how they can film these people out on the roads doing suicidal poo poo and just keep rolling to get some footage. The show itself is pretty funny but the producers need to be a little more responsible.

The times I've watched the show it seems way better and more educational than any other reality program. As confidence building and vehicle handling exercises they teach them to do some basic stunt driving maneuvers like handbrake and J-turns, and you better believe I practiced that stuff when the opportunity presented itself.

Canada's worst driver is a really good, honest, and educational show. They're really trying to get through to these poeple. It's also a powerful indictment of our entire licensing system being broken as gently caress that there aren't systems in place to get people like that off the road.

But we've decided to build a society where taking away someone's license pretty much removes their ability to participate in society in most places, which means the bar for safe driving has to be practically non-existent.

Actually there's been at least one instance (maybe two?) where the cameraman jumped out because they were afraid for their lives, in addition to them all refusing to drive with Krystal on principle.

Edit: Yeah, she had undiagnosed and untreated borderline personality disorder.

What are you going on about? The TV show is almost entirely filmed on a closed course. The clips where you see these people on the road are from the pre-show nomination footage, where the camera crew is just tailing them while there's a GoPro in their car; or from the initial drive to the abandoned airfield. No one is coercing them into driving like morons.

if you want to blame somebody for keeping her on the road, blame the insurance companies who apparently continued to consider her insurable even though she's had so many accidents and incidents that her premiums are $10,000 a year.

I understand that, but if you have video footage of a person committing multiple crimes, putting many people in danger, you call the police and give them the footage. You don't fly them out to Ontario and put them in another vehicle to get more footage. Everything shown in that video between 16:35 to 20:35 is on public roads. The black vehicle is a vehicle provided by the show. Nobody is coercing them to drive like morons, but they're providing them a vehicle with which to drive on public roads, and then filming it knowing they're going to.

I understand where you're coming from, but what difference does it make? As long as they have a license, they're going to drive like that regardless of whether they're on TV or not. If the broken-rear end system decided that despite all of her accidents (i.e. demonstrated incompetence) she's still allowed to operate a vehicle, that's on the insurance company and the province, not the producers of the TV show.

Providing her with a vehicle doesn't mean anything. Would you blame the car dealer who sold her the car that she crashed? She's an adult and she has a license.

Those people drive like that every day, the hope is to train them a bit to stop being quite so dangerous. Also they did get the police involved a few times. One lady bragged about a bunch of hit and runs she did and they used the info to bust her. One could ask the government why they aren't using this video evidence to take people licenses away, they have the power to actually deal with these people, not a TV show, they can only document the evidence. But driving is a god given human right in Canada, doesn't matter how many people you've run down or cars you've totaled, you just pay more for insurance.

I happened to see the group with the guy you're talking about, and I can't believe he's the one you singled out. The punk whose brother murdered a man with a truck, and who has himself killed someone with his lovely driving, and also beat up some guy in traffic, is INFINITELY worse.

That's weird because I've only ever seen electric ranges like that with dials on the back (at least, of the handful I've lived with and can recall). Makes me wonder if it's a balance between "reach over the stove" vs. "in range of children" or something.
