autonomous vehicle lane

Youtubers and news channels have been to the location and showed the area to be a lot brighter than the original dashcam footage, the sensors detected an object 6 seconds before the impact.. Then fractions of a second later its a moving object then its a bicycle and that emergency braking was required. But they disabled the braking because they didnt trust the system. What does that tell you? The car knew it needed to brake but they disabled it and it did not warn the driver either.

But my question was would a human controlled driver have detected the hazard and been able to respond in time?

Correct, nobody hurt or injured in that. But how can they claim the system is not 100% self drive and that the driver must be in control. When the driver clearly wasnt in control. The system knows if the driver is holding the wheel so why does it not pull over?

But that was not an autonomous vehicle, as none are currently commercially available, it was a driver assist function that was being utilised by the driver. I've no idea if that particular system incorporates steering wheel detection. From some of the videos I've seen posted of individuals driving such equipped vehicles and taking their hands off the wheel I'd say many don't.

My current car has lane assist ... if I take my hands off the wheel* the car will auto-steer to keep itself in the current lane (as long as the road is straight or only has minor bends - tighter bends tend to kick out lane assist). After a few seconds a warning image comes up on the dash to tell the driver to take control of the steering. (I've not left it long enough to see what happens next - and have no intention of doing so).

* tested on a clear, quiet road with my hands ready hovering over the steering wheel.

What does it do in motorway roadworks, where there's lines continuing the original lanes, but superceded by studs/other lines moving you into narrower temporary lanes?

It's eminently fallible - all the various lane-departure warning/assist systems use sensors mounted in the underside of the bumper to detect the lane markings. If those sensors get damaged or clagged...

These systems aren't new - lane warning systems have been in production since the very early 00s, and in Europe since about 05.

To add petrol to the fire!! ...how about adding radio frequency signals to cats eyes and the red and yellow studs on the motorway to let autonomous vehicles detect which lane they are in and assist/guide with following the road around bends.


also traffic jams are not caused by lack of space on the roads..
its mainly lack of concentration, slow drivers and road accidents.

Or steel rails and flanged wheels ....

As the UK begins to brace for autonomous vehicles on our roads,
Do you think the government could introduce autonomous vehicle lanes on our motorways especially on our smart motorways? This would reduce accidents and traffic jams as well as reduce the anxiety of other drivers (normal operating vehicles) as they know that autonomous vehicles are in their own lane, except when exiting or entering the motorway. Maybe something Martin could champion this to the government!

what are your thoughts?

My thoughts are it would increase accidents and traffic jams, a nasty double whammy. Why would you think otherwise?


p.s What autonomous cars? There arent any.
p.p.s. If autonomous vehicles, should they appear in our lifetimes, are unsafe enough to need their own lane, they shouldn't be on the roads full stop. They should be "better" drivers than the average driver, at a minimum or whats the point (unless its just to make taxi companies more profitable, albeit with more dangerous cars)

With the accident rate increasing with autonomous cars, are they really safe to let out in public?

Accident rate is climbing.

Well, yeah, it was '0' 30 years ago, so it sure is climbing!

Are you missing out all the other crashes that are happening all the time with humans at the wheel?!

I wonder what all those that said the accident rate in them was very low will say now?

1. It's still low

2. There are barely any actual autonomous cars on any roads. Tesla's is about the most advanced, but the human is expected to remain in control of the car. Some humans seem to forget this.

Surely just "a bit closer". At 70 mph the thinking distance (which would not be needed) is 21 metres, but that still leaves a braking distance of 75 meters.

No. The plans are that autonomous cars will be able to talk to each other (manufacturers to decide on a common protocol, good luck!), so they could follow inches from each other - they'll know what's going on ahead without having to see.

Fine, but what if the one in front stops or slows rapidly without braking, i.e. collides with something?

Yep, big crash! So they'll leave a bigger gap.

Tesla claim's that its an assistant and not a 100% self drive. Why does it not deactivate when your hands are not on the wheel or when the driver actually leaves the driving seat?

It does, it give multiple warnings, and will eventually pull over if the driver refuses.

It's easy to think of scenarios where autonomous vehicles can't avoid a crash. You can even think of plenty of times a human would do better. But you can't avoid the other, make up a number, 90% of the time that an automomous car would be safer than a human.

What does it do in motorway roadworks, where there's lines continuing the original lanes, but superceded by studs/other lines moving you into narrower temporary lanes?

It doesn't work - it's looking for lines either side. It would de-activate here and you're on your own. It's not advertised as anything more.

If there were one lane, on a three lane motorway, say lane 1, for autonomous vehicles and the German lane, 3, then the rest of us mere mortals and HGVs will all have to use the middle lane, 2.
That's not fair!

For every 10,000 errors
made by a human driver,
an autonomous vehicle
will make just one

If that stat can be relied upon then I can see in the not too distant future where it would be near enough unpractical to drive manually because A) insurance price would be prohibitive or government would introduce so many legislations to deter people from manual driving.
