Most states allow you to go without insurance by fronting the cash. It's called self-insurance. You put up some minimum amount, file a form with the state DMV, and keep the approval certificate in the vehicle like normal. It's relatively unknown for individuals because most people have no desire to lock up tens or hundreds of thousands of spare dollars just to avoid car insurance. As far as I'm aware it's primarily u…

    That's BS on it's face. Most states don't allow it or they restrict it to big business and government agencies.
It's 11 states, covering roughly a third of the US population. There's a quite few more if you own significant numbers of vehicles. You can s/most/many/ if it makes you feel better.

    Most people's money isn't making a return greater than what insurance would cost them.
You wouldn't be making money on a self-insurance bond either. It's locked up with the state or in a surety account. You can also expect to pay a significant fraction of your regular insurance costs to maintain a surety bond.

    Second, this completely ignores my point about credit.
Credit lines expire when you die (say in an accident), they're not guaranteed to pay out the full amount at any particular time, and the courts probably shouldn't go around binding third parties to pay out on your behalf.

States' interest here is in guaranteeing that there will always be a minimum amount of money to compensate victims, regardless of what other financial shenanigans you have going on in your life. That's not a standard that lines of credit and investment accounts meet. Self-insurance is simply a terrible option for most consumers, so no one does it.

I don't think you're understanding. The point is that 20 people in a row will take advantage of your buffer to slow you down again and again and again, which makes you get to your destination later... because they're being selfish to get somewhere faster, and you're not so you get to where you're going slower . We're not talking about where they're changing lanes to take the next exit. We're talking about where your…

I understand perfectly, 20 years driving, I think people just don't like that the safe answer is to be slow. You will not fix others behaviour, so your options are be slow and generous, get out of the chaotic lanes (unless that's all of them), or join them and be aggressive, claim space, be stressed and annoyed your whole trip. There is no solution to traffic here sorry, this is more about managing your own frustrati…

It is more dangerous to be slow and have people constantly merging in front of you, rather than be slightly faster and not have all the merging. Accidents happen when vehicles are going different speeds, all things equal.

I got one of those dongles from my insurance company that plugged into the ODB2 port and reported my driving habits. I was a bad driver.

Maintaining a safe following distance is incredibly challenging on busy freeways where hard braking is often 'required'. Most people have likely found themselves in this situation: vehicle changes lanes in front of you; you slow down to maintain a safe following distance, another car sees a gap and changes lanes in front of you. Repeat for your entire commute. Incredibly frustrating, and I've driven all over North Am…

I leave a lot of distance, but people rarely change lanes to get in front of me, because the person I'm following isn't going any faster; the separation is in d not v. Most people who do change in front of me are there only briefly on their way to an exit, which means I'm increasing the fluidity of the traffic flow, so I'm happy about that. If I didn't leave space, they'd likely hard-brake in front of someone, causing a slowdown.

It's frustrating because someone is taking your safety buffer as their opportunity to travel faster. And it results in you having to travel slower and slower to maintain the gap that is constantly consumed, tragedy of the commons style, by opportunists.

Slow down a bit to create another buffer. You can even do this before they have merged, as part of the bit where you allow them to safely merge. I think if you reflect a bit you'll find you are being the same kind of person as them, if you are getting angry that you have to slow down and give up space for someone else. I understand some people can be aggressive though, that can be frustrating regardless of the outcom…

you missed the fact that most people either aren't signaling or do it right as they're already cutting in.

that's hardly safe when it's already tight with a safety buffer as it is.

provided they use a signal as required by law and taught in the drivers handbook, they'd likely be let into the new lane without any judgement.

If you actually want the safest option then you should merge all the way right and keep slowing down. Noone is going to merge right if they are trying to go faster, they will only do it to get off the offramp. Meaning the gap will reopen as people exit through the offramp or merge left into faster lanes. If you choose to go in the fastlane in traffic you should understand that it will have people who do not care abou…

> If you choose to go in the fastlane in traffic you should understand that it will have people who do not care about the following distance as much and are just trying to go as fast as possible. It's not about choosing to go in the fast lane. It's about the fact that in heavy traffic, you have no idea which lane will be fastest, because they're all heavy and which one is fastest keeps switching. > I have found that…

Everyone merges into your lane

Their old lane speeds up because many cars departed it

Everyone merges back to their old lane

You're back where you started.

Inter-car distance is always a safety factor but can immensely reduce lane throughput. There is a compromise. I remember a few decades ago, in California at least, they suggested the drivers keep a one-car length distance from the leading car for every 10m/h speed. Funny that I had to convert it in km/h.

not dying >>>>>> lane throughput

Inter car distance is highly irrelevant as the overall speed will quickly drop due to excessive braking due to tailgating. Maximum throughout is around 60kph. You keep 2s distance if you want to be safe. So at highway speeds that is around 50 to 70 meters

That seems like a surprising enough statement to be backed up by data. What is your source?

Everything I've read points toward larger margins of safety (longer distances, slower speeds) being safer.

American road laws are insane here. The law should be simple; you must be in the outside lane at all times unless you are overtaking, and once you're done overtaking, you should merge back into the outside lane.
