1930s cable operated drum brakes. They never updated it. But it's still good practice, there are many situations where the decision to brake isn't immediate.

It's not good practice as a modern car takes nothing like that distance to stop.

So your car is useless, I'm surprised you haven't turned that annoying feature off. It's actually slowing you down for something which isn't a hazard.

4 times the distance. Twice as long.
Don't they teach the calculus any more for O level?

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.

Anyone who requires the aid of a warning system is obviously not paying attention and shouldn't be driving.

Agreed. Ditto for anyone who requires a seatbelt.

I did and misstated. It was not relevant to reaction time. Point is it is much easier to measure time before you would reach where the other vehicle is than remembering so many car lengths at various speeds.
Times I might need calculus, I don't remember any of it and I had a technical career. Never needed it.

Nearly half of all RTCs have driver not looking properly as a contributory factor. The Transport Research Laboratory have concluded that the universal adoption of auto braking systems would produce a significant reduction in accidents and of the severity of accidents.

That may be true but with no automatic action a collision is inevitable so you take your chances and hope there is no 40 tonner behind but he may be smarter than you and has already slowed. . You still get some alert and can possibly take evasive action.
Moral of the story: Pay attention. Look out the window once in a while

Precisely. Not that the egotists posting here have thought of that. Or indeed, much of anything, other than the overwhelming desire to get in front of the person in front of them, skipping over the fact that there's someone in front of them, too, for mile after mile after mile. Driving on the public highway is not a race, not a contest. The only thing you gain by driving like a dick is the scorn of those around you. If you want to drive like that, go racing. Where you will promptly discover that you can't drive for shit.

And I would suggest modern cars should take part of the blame. The Peugeot we didn't buy would have had me using the touch screen device to set the heating controls. And since it's a touch screen, you have to look at it to know what you're doing.

It will travel at 7' 4" per sec. 60mph = 88 ft/sec is the correct ratio

Next time I'm driving along, I'll stop, get out and use a tape measure, then.... oh that won't work.

It's easier just to use you judgement to know how far back you should be.
You don't need calculus for the above.

What a load of s**te you post. I can get from Central Scotland to London 2 hours sooner than a driver who obeys the law.

Instead of at your speedo and all the motorway bridges for pigs. Remove all speed cameras, increase attention and safety dramatically. Speed cameras don't make people drive slower, they distract them.

Don't get me started on that one.
Shit! Too late.
I find it amazing how our state requires seat belts but several years ago banned the law for motorcycle helmets. It's all about revenues and they prove it with their "Click it or ticket" enforcement. I have never worn a seat belt and never will.

You surprise me. I thought I was the only non-seatbelt wearer left. Mind you, when I hitchhike I often encounter lorry drivers who don't bother, and about 1 in 3 of the people I pick up don't wear one when they see I'm not.
