alt Hacker NewsI 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. It would frequently beep at me to let me know that I had braked too hard. I was mystified. "What should I have done differently," I'd think, as I raged at the objective machine that judged me so.
The next time my brother came to visit, he called mom. "Oh, and presidentender is a good driver now." I didn't put the pieces together right away, but it turned out that the dongle had actually trained me, like a dog's shock collar.
The reason for my too-frequent hard-braking events wasn't speed, although that would be a contributing factor. It was a lack of appropriate following distance. Because I'd follow the drivers in front of me too closely I'd have to brake hard if they did... Or if they drive normally and happened to have a turn coming up.
Over the period I had the insurance spy box in my truck I learned without thinking about it to increase my following distance, which meant that riding with me as a passenger was more comfortable and it beeped less often. Of course since I'd been so naughty early during the evaluation they didn't decrease my rates, but I think the training probably did make me statistically less likely to crash.

Not only are you less likely to crash -- you're less likely to cause a crash ten cars behind you.
This diagram changed how I think about following distance: https://entropicthoughts.com/keep-a-safe-following-distance
Thanks for sharing. I'm genuinely impressed to hear someone publicly share a story of growing self awareness and improvement.
On the other hand, at age 20, with very high premiums, I got one of these devices which never beeped except on a few too-short exit ramps on highways in my city. The choice on these exits is to slow down traffic on the highway, or endure a "hard stop" by braking immediately when you are on the ramp, and coming to a full stop at the stop sign.
Just a few of these was enough that my "discount" was only a few dollars. I regret giving Progressive my driving data.
Safe following is super important. Few years back about a month after I bought a new car I was driving to work keeping a larger than normal gap thanks to a bit of "new car" anxiety. I was in the left lane, keeping pace with a cluster of three cars ahead of me, two of them tailgating. I don't know what happened but within seconds the middle car swerved, side swiped a car in the middle lane then rear ended the lead car while the trailing car rear ended them. Four cars smashed up right in front of me. I was fine because I had plenty of time to slow down and pull onto the shoulder to clear the chaos.
Is there any vehicle that uses it's sensors to make a gentle suggestion about following distance?
It's probably the best single thing anyone can do to improve safety. It also reduces wear-and-tear on your car, and increases your fuel economy as a side benefit.
Why hasn't gamification of safe driving habits been built directly into the car itself before now?
I can only speak for Europe, but driving too closely to the driver in front is unfortunately how 90% of drivers drive.
Unless it’s in Netherlands, where it’s 100%.
As a passenger, I really notice the difference, and I wish more drivers (including professionals) would learn as you did. It probably saves energy as well, especially when driving in cities, although I guess it's marginal.
Kudos on you for acknowledging that your behavior changed! It is depressing how many people online are convinced that the emergency braking systems are too aggressive. The best is the cohort that insist these systems will be what causes accidents.
I have a friend who would also follow too closely to the cars in front and got one of these. Her rates went up and she eventually got into an accident (no injuries to anyone) because she would follow too closely and still break too hard.
Now she still has the machine, still follows too closely, and still breaks too hard in her new car...
Good it worked for you though!
People here in Tokyo follow at obscenely tight distance on the freeways and motorways. Drives me crazy. Don't have the data, but having driven here for over 20 years, I’d venture that short following distances must be one of the main causes of accidents on these types of roads. People are otherwise generally cautious and attentive drivers. When I’ve expressed frustration about it to locals in the past, the response is often “but if you leave more space, people will cut in!” To which I respond, “okay, and?!” I feel like a single big media campaign to improve following distances could result in a big improvement. So frustrating.
I'm always surprised at the number of people that follow too closely.
This always stuck with me
I was recently driving a friend and hit a mile-long backup at a freeway exit. At some point in the lineup, a car abruptly cut in front of me to merge into the line. The friend asked "why'd you let them in" - but I didn't let them in on purpose, I was just maintaining a reasonable following distance which people seem to interpret as "hey cut in here for free"
If you have to brake hard, it is still important to not brake harder than necessary, to give the cars behind you the best possible chance to react in time.
As one of my friends put it - driving in the US is like being in Whacky Races.
While i find everything about this post thoroughly dystopian; I will state that I don't break harshly, just about ever, my car still has it's original breakpads (they still have some life, about a cm and a half to two) and it had 107k on the odo. Never been in an accident outside of getting break-checked by an insurance scammer when I was 19, and a head on when i was stopped at a stop sign.
Although I keep a varying follow distance, if there is an open lane immediately adjacent to me, I don't care if i'm tailing someone a bit, but if I'm boxed then you better believe it's 6+ car distance.
The problem with increasing your following distance though is now you get other drivers cutting in, and you’re back to where you started
> It was a lack of appropriate following distance.
Not in my case. I keep plenty of following distance, 9 times out of 10 my hard braking is because some idiot cuts into that following distance and brake-checks me.
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 America - there's practically no major city where this doesn't happen. If you're not maintaining a safe following distance on city/residential streets, that's a different matter.
