So yet another bit of technology to protect dangerous drivers from themselves.
I wonder if it will actually recognise bikes or just see straight through us like so many automatic electronic gates and barriers do?

It's a complete non-issue. It'll be standard fitment on most cars within 10 years or so just like ABS. No need for more laws. Rolling Eyes

Has a laser camera on it, so it should see us too. Insurance could get interesting if you hit someone and the system was broken. Laughing

It could save lives, by braking when the driver should be braking anyway ....

The driver then has the excuse I obviously couldn't have stopped because even that system didn't stop me, therefore not my fault.

Colleague at work has been test driving potential replacement company car for himself.

At least one had an adaptive cruise control (less severe but same principle I expect to the emergency braking system). So if you're on the motorway and the vehicle(s) in fron t slow, as they do, it maintains the gap. Then speeds up again when needed.

I did wonder at the time if it would see a motorcycle. That's sports motorcycle with narrow profile. I'd image (hope) a lardy tourer with hard panniers would be visible.

Total stupid system. If you aren't capable of paying attention to what's in front and able to break in time then you should have your licence removed. Better to just keep the idiots off the road

How does it respond to oncoming traffic? Perhaps you are overtaking a car and it sees one in the distance, will it fuck you up? Laughing How about if your a twat and the overtake is lot closer than it should be?

Secondly, most vehicles lose the ability to steer under heavy braking. 99% of the time I would prefer to keep my speed and have agility instead. This system takes away that choice.

I quite like the idea, if the world was perfect it would be great. However the real problem is lazy, hesitant drivers - incapable of split second decision making. Going slow does not make you safer Laughing

Great system I think, because sometimes drivers aren't looking... they're too busy texting or playing with a satnav or got their head in the cockpit when they should be looking outside.

BUT... implement additional technology into the car... such as sensors which detect a crash (alongside airbag sensors) which will alert emergency services if it is above a certain severity threshold. And if the AEB takes action... automatically send information to a "shit driver database" which the MIB have access to, so come renewal time you have to pay higher premiums cos you were obviously a higher risk and would have had an accident.


That would then hopefully prevent drivers relying on it, and actively drive to avoid its use, which would lead to an improvement of driving standards over time, as everyone increases distance with the car in front to avoid an AEB incident where they really wouldn't be at fault if there was a domino effect of AEB braking.

Why wait until then?

Dibble could stop lurking in bushes, attend vehicle collisions and hand out driver improvement courses under the threat of without due care and attention to the failed party or parties.

A collision generally means that someone has actually failed it. Why the focus on bagging drivers who haven't?

Yes, I know, it's easy and it rakes in the revenue and boosts the numbers. But it's not right.

Don't think 'right' has ever been involved in political messages showing they are 'making a difference'!
League tables, however....

They don't... Most vehicles have ABS and can steer perfectly well under braking. That is one of the major selling points of ABS.

You would certainly be wrong 99% of the time - the fact that braking offers the greatest rate of change in momentum you can get on a vehicle shows that in most* cases it's the fastest way to prevent an accident.



*notice I said most - I'm sure you can concoct some thought experiment that shows in all the cases you can think of a swerve whilst gunning the throttle is the best course of action, but I'm talking real world here

Given that they're not going to keep 'the idiots' off the road I'd much rather they had aides than not...

Your infallible self image scares me a little though - I assume you don't consider you're one of 'the idiots', so that means you have 100% perfect attention at all times*?

The thing is, these systems are just stepping stones to full driverless technologies - the manufacturers know that tested failsafes are an important part of allowing fully autonomous vehicles.



Hint: it's a trick question: If you answer yes then you're deluded and a prime candidate for aides, if you answer no then aides may just be helpful some time.

Sure ABS allows a car to steer, because the wheels are not locked up. That does not necessarily mean the car will go in the same direction you are pointing the wheel. Sudden weight transfer to the front wheels does not make a car particularly stable. This can be seen in many liveleak crash videos.

I have spun an ABS equipped car on a roundabout under heavy braking. (this was a long time ago)


Braking is good, but as an example yesterday - poor obs I did not see the lorry infront was braking and had locked wheels on trailer. I was doing 60mph on the bike and had a large gap. I did stop in time but as I got closer I was ready to release brakes and go onto the wet grass. Grass is not going to hurt as much.

Depend on the car. I know plenty of cars which will steer well under heavy forward weight transfer under braking, and plenty of cars that will understeer much worse than that when you're nowhere near the pedal. It's more about the car and chassis setup than weight transfer itself.

You said most vehicles lose the ability to steer, which is incorrect. Trying to switch to a slight loss of stability is kinda disingenuous.

Loss of traction sideways is very different. ABS helps you get close to maximum braking whilst still retaining control, if you've already lost control then you're on your own...

So braking worked... Isolated examples mean very little. I can guarantee that over 50% of vehicles involved in accidents* could've avoided them by braking earlier.




*that's based just on pure logic! I suspect the real % to be much higher.
