Is that why in Youtube "whoops he f***ed up and crashed" videos, cars make silly "dong!" noises when crashing?
If the car's figured out it's going to crash, why waste time informing the driver with a silly noise, instead of just applying the brakes?!
I could have got it as an option on my Subaru but it is now standard on some Nissan's. This includes emergency.
Cited article says dings give 5 seconds extra reaction time. Most places here call for a 3 second rule which means following distance should be 3 seconds when you reach where the vehicle ahead was when you start counting. Here in Delaware the law calls for 4 seconds.
Very few people pay attention to this rule.

?
On Chicago area expressways, a 3-second following distance is an invitation for a car to cut in front of you and fill the void.
Five-second following distance and a gravel hauler (spilling gravel) will cut in. LOL

Gonna happen soon according to this:
Soon is 2022.
I thought most modern cars had auto brakes.
It's 2 seconds in the UK (I guess we think faster). I usually leave 0.5 seconds, or 0.25 seconds if the guy in front is pissing me off. How on earth can anyone take 2 seconds to react? 2 seconds gap is very useful though for me to pull into.
We don't have drum brakes anymore. And we all have ABS.
Because it wont necessarily get it right every time and just applying the brakes may produce an undesirable result, most obviously when someone is tail gating you and giving them more warning that you are stopping would be better.
The car is just alerting the driver to stop texting, put down the phone and focus on driving the car into the impending accident.

Nor me. They're talking s**te.
It happens to someone, because if I see a "safety gap", I go into it.
I had picked up this ruling when I last took an online defensive driving refresher course. Doing so results in 15% auto insurance cost reduction. The old rule was so many car lengths at certain speeds. We all know it takes 4 times as long to stop at double the speed so this rule makes it easy.
Like I said, few abide particularly on higher speed roads. I try to drive with the flow myself and know that leaving such distance is bound to get me cut off.
The problem with that is that the car might not have such a 360 view of the world as the driver. There's no point slamming on the brakes to avoid hitting say a mini in front if by doing so you're do so you're going to get a 40 tonner in your arse. In that scenario swerving and clipping the car in front would be a much better response but at the moment cars can't do that autonomously and even if they could they still might not have rear view cameras to make that assessment.
I guess it can help to wake up a sleepy driver, but from what I've seen on Youtube crashes, it's FAR too late a warning and happens AFTER the crash.
Plus, every one I've heard is a silly little ding noise. It doesn't sound urgent, it's just a noise like you'd get when you don't put your seatbelt on. I'd imagine the driver would be thinking, "I wonder what that noise is", checking the dashboard for a warning light, then misses looking out for the collision altogether. I'd call it a stupid distraction. It's like the passenger noticing the driver is going to crash and saying "Excuse me...." "Yes dear?" "See that truck in front, you'd better...... oh too late." A better system would be the passenger shouting "Look out!" or the car making a very loud warning noise, not "ping!"
I can't believe people actually attempt to measure a distance or time while driving. The safe distance should come naturally, and changes according to your reaction time, the condition of your car, the weather, if you can see through the car in front [1], etc, etc.
[1] Why are windscreens not allowed to be tinted, or the driver's window, but you can tint the rest so the person behind can't see a hazard in front of you?
It depends on the car. Some DO stop before a rear end crash.
Some vehicles the steering wheel vibrates vigorously to get your attention along with the chime. Then, if you have a death wish, it will automatically brake. But nothing replaces common sense.
As far as people cutting in front of you when you leave the gap you're driving too slow. As Ed said, keep pace with the traffic or take a less traveled road where you can poke along and not slow traffic down to a snails pace.
4 times the distance. Twice as long.
Don't they teach the calculus any more for O level?
I never drive too slow. There's always a car right in front of me holding me up!
What I find hilarious are people who slow down because they think they're annoying the "tailgater". What they're actually doing is making it easier for me to overtake.
Maybe he meant long as in length of road? :-)
Anyway, nobody should be doing calculus while driving, they should use gut instinct, it's far faster.
