Speed limiters mandatory in new cars from 2022

System

My only worry is that people start to rely on it too heavily. Living in the countryside there's a lot of 60MPH signed stretches of road which would see you in a ditch if you try to go anywhere near.

AEBS is also going to be mandatory too. I've done roughly 300,000 miles or so in trucks equipped with it from multiple manufacturers and they all suffer far too many false positives.

I think it's great news. I have always thought that technology was the way to reduce death and injuries on the road. Can you imagine a pilot saying "take that black box out of my plane. I want to break all the rules and not get caught." If a collision occurs law enforcement agencies should have access to all the data possible to determine the cause of the collision.

Which is more often than not driver carelessness NOT speeding.

What was it someone said today - dodgems have speed restrictors on them they still seem to manage to crash?

Educating people - as they used to with TV ads - of the fundamentals of such things as mirror, signal, manoeuvre and what lane to be in on a roundabout and how to traverse a roundabout would have a bigger impact on accident rates.

It wouldn't on 2 counts, 1) the driver should be a safe distance from the vehicle in front , safe as in allowing appropriate stopping distance for the road conditions 2) the driver behind may also have a modern car which features autonomous braking systems.

The problem with 2) is there are currently around 40 million vehicles in the UK that don't.

The AEBS system on my truck regularly gets triggered when going under bridges on motorways with nothing in front of me, let alone situations like a central right turn reservation with cars in on a tight left hand bend. Too many false positives with AEBS at the moment.

I recently had a hire car that had a “heads-up” display showing the speed limit... I was thrilled with it until it showed me 110 on a single carriageway section of derestricted road then 30 on another bit of derestricted road but back to 60 on the next section of 40 mph limit. It’s a good idea, but the practice has still a way to go!

I think we're 20 years away from it being reliable. Theres going to be a big onus on councils to ensure speed limit signs are up, maintained and correct which they neither have the money nor interest in doing.

As has been said, i think 2021 will be peak year for new car sales....

And nothing to do with the poor drivers the rest of us subsidise.
I rest my case.

As long as it's fitted to police cars too, or it will be very unfair on getaway drivers.

...and will be the death knell for the Hollywood car-chase scene!

Take my example of driving on 40 and pick up 30 sign, if the car suddenly apply break on itself to 30, it will cause accident for the car following me.

The car won't suddenly brake, it would limit engine power until the 30 is reached, so you'd coast down to the new limit.

If 2 is not possible then see count 1,
My car has AEB and in the over 5 years of ownership, only 1 real false positive, once where it has definitely hindered a collision at a Y junction, the few other times just the audible alert has come on , but I could see why it would eg car turning ahead and I'm approaching too quickly for it's setting.
My friend has a quashqai and every journey that bleeps away, I don't know if it will actually brake the vehicle on that model.

As for 'false positives' I think it depends on the sensitivity setting.

My car has 12 proximity sensors and radar front and rear.

At the highest (most sensitive) setting the alarm is triggered much more often.

It has only applied brakes once - when an oncoming truck was overtaking.

No system can be 100% infallible.

Problems will always occur when humans make the mistake of thinking that they have no role to play in decisions.

Whenever I engage reverse gear the rear camera comes on and a warning message appears on the screen 'Do not rely solely on camera input.'

I dread to think what some folks would do without that warning!

Sat-Navs directing people up one way streets is also a good example as some actually do it.

Lemmings going over a cliff comes to mind.
