Many cars already have emergency measures for "something is suddenly in front of me". You as a human are not able to be predictive in such situations, you have to react... and likely your reaction time is slower. I've had a couple of times where our car has slammed on the brakes while I was still moving my foot to the brake in this sort of situation.
A typical human reaction if something suddenly appears in the road in front of them is to swerve wildly or do an emergency stop without any consideration for who is next to or behind them - this leads to a lot of accidents when someone e.g. reacts to a bird/cat running out in the street.

In most motorway situations, the response to an accident further ahead is to simply slow down safely, definitely not to be weaving into other lanes. Existing non-AI cars can already do this better than people. When you slow suddenly because you notice the car in front has slammed on the brakes, you are most at risk of the person behind piling into you because they didn't notice. Sometimes you can even see them in your rearview when they suddenly go "oh crap" a couple of seconds late and have to do an emergency stop. Very simple tech fixes that.

well you destroy your own argument.

If you only consider what is in your lane that is reactive. If you watch action in multiple lanes then you can predict.

As mentioned previously one in 8 collisions involves tailgating, if you cannot stop if the car in front applies the brakes you are the problem.

Depends what you expect on Motorways on the way up north a few weeks ago there was a bed base in the carriageway, I also have had lorry tyre treads ,pallets ,rocks, 40 tonne lorries and upside down caravans enter my lane about 10 feet in front of me.

Its not just reactive it needs to be predictive.

I think the double drainer stainless steel sink in the outside lane of the M4 was inneresting, though not as inneresting as the 5cwt escort van I suddenly realised was actually stationary in the outside lane and just managed to squeeze the Zodiac between it and the central reservation.

Then again suddenly realising that there was a little white car being pushed sideways across the front of a Tesco artic was even more inneresting, especially when the artic driver put his brakes on & said car shot across the carriageway, hit the central crash barrier & eventually came to a stop in the middle lane facing the wrong way.

I never did hear what happened about that.

I can see a market for these stuck to the outside of your eyelids.

I would imagine on motorways you will not end up having to be eagle-eyed every second because it will be far more reactive to an emergency. Maybe only in certain cases but still useful.

Got to say I look at all the stages between Adaptive Cruise Control and fully automated and think - I'm going to have to keep my eyes on the road so I may as well have my hands on the steering wheel and do something.

Erm, do you mean like this...?

Is that fitted as standard on all cars? This is exactly my point, unless all vehicles use it then any AI vehicle has to assume none do. It may still help them be even smarter - they can see an issue 10 cars up the road before it's visible - but it's an extra thing to build in.
If you start from a clean slate where all vehicles are autonomous and use standard protocols, the actual computational cleverness can be far less because every vehicle can negotiate with the others.

[eek]

We don't have anything this advanced, but I can definitely say adaptive cruise control is a wonderful feature in that direction in terms of reducing fatigue. Tracking your eyes seems a clever idea.

Like a taxi? But seriously, this tech is already operating in some locations - the Tesla self-driving is only one of the more high-profile examples which has logged millions of miles of autonomous driving including roundabouts, slip-roads, busy city streets and country roads.

The hardest part IMO is each car has to do this purely on its own - if things were standardised and all cars could talk to each other it would be presumably so much easier from a tech standpoint.

nah we will centralise them like the smart motorways did and the broken down car app can break on all 'smart' motorways. You know it makes sense, some parcel company or supermarket will do that to save a penny every 100 miles.

I doubt it'll happen in my lifetime, but I'd really welcome cars - or some kind of similarly flexible transport - which didn't need me to drive.

..though don't try it on the M25 as you will fall asleep.

Drivers will be legally allowed to take their hands off the steering wheel on Britain’s motorways for the first time as long as they watch the road, after the government approved another step on the path to self-driving cars.

The driving-assist feature in Ford’s latest Mustang Mach-E model, which allows the vehicle to steer and accelerate but also monitors the driver’s attention to ensure their eyes are on the road, will be permitted by the Department for Transport in a first for Europe

The BlueCruise system, an £18-a-month subscription add-on to the £50,000 electric car, uses radars and cameras to track road markings and other vehicles, and an infrared camera in the car to ensure the driver’s eyes remain on the road ahead.

Waiting for the first prosecution for misusing hands free and inappropriate use of hands

My brother tried similar in his Honda.

Set cruise control to the road's speed limit and then let the car use its own auto braking and lane control to drive down the M23.

He didn't go to sleep as was bricking it but said it did very well.

I've got a new Civic e:HEV with the adaptive cruise and lane keeping and it works very well. On main roads I use the lane keeping all the time and just rest my hands on the wheel. You have to indicate to move lanes cause it doesn't like it if you don't and tugs you back but once used to it there are no issues. With the adaptive cruise I use it in stop start situations such as going through roadworks, set a speed a bit above the limit and the shortest follow distance and it locks onto the vehicle in front and simply follows it speeding up and slowing down as necessary. I also use it for fun cause it shows the vehicles in front and coming up the sides and the actual vehicle type in the dash. Little lorry, bus, car and motorbike icons moving along the road with you in the dash, very cute
