The idea is that people wouldn't own the cars, you'd call one and it would take you where you wanted to go and you would pay for each use. Once you are at your destination the car is then available to be called by another person so you would not need as many cars to exist.

How do you control the cars, physical tracks with signalling?, loops in the road? Sensors/GPS on the cars? Moving GPS isn't that accurate (+/- 5-10m) unless you pay for the high grade signal (public signal is limited, there are encrypted commercial and military signals with higher precision), plus the number of sensors you'd need.

Automation is fine in a controled envionment - add pedestians, animals and other hazards and you might be better off with manual

Google have been testing a driverless car recently, so far the tests have been very successful with the car covering many miles of California without incident caused by the car.

Well I would expect such a system to be adopted EU wide once the technology is available.
And if it's not?

For the cars that people already own it would be quite simple to introduce legislation banning their use on public roads.
Which would be political suicide.

It is for this reason though that the introduction of drivleress cars may take a long time even though they may be available in ten years time.
If it's ever actualy introduced, rather than people choosing whether or not to have one.

I'm just not sure if people would object to giving up the option to manually drive the car.
I'd object, and most people I know would as well.

That said with issues like peak oil and climate change it's likely that in the future the average person won't be able to afford a car.
That's why they've been working on alterntive fuels.

The other thing to bear in mind is who else uses the rent-a-autocars, getting in one with etched windows and vomit... Can't see CCTV being workable across a huge fleet.

Plus would there just be one car request place, or multiple competing operators

1) In Scotland, National Speed Limit signs legally mean nothing on a Motorway, so we have 70 signs instead. Seems slightly odd to me going down to an English motorway and seeing a NSL sign; I'm sure it's just as odd for you coming up here!

2) Motorways are the safest roads under the current rules. When you change those rules, then the safety of the road may well change. Bear in mind that most people do adhere to the motorway speed limits (in my experience anyway). We do need to take the increase of speed into consideration when discussing this. I'm all for raising the limit to 80 in appropriate areas, but we do need to actually look and see what effect the change is going to have before making a decision.

Furthermore, I really do think that a blanket 80mph restriction would be foolish, and that the 70mph limit should remain on roads where it's needed. The 80 should only be applied on certain roads where it is regularly safe to travel at such speeds.

PS, come up and have a drive on the M8. You can enjoy a drop to 60 another drop to 50, back up to 70, then right down to 40 over the Whitecart viaduct :lol: (All bar the last one are actually pretty sensible for the road in question).


No flippin' fear. they still eat their own young up there!:D

I would. I love driving on a good road with lots of twists. Also love exploring small lanes wondering where does this lead? I'd love to see the google car explore some lanes in Devon. Streetview Cars have often stopped thinking "this can't be a road" - yes that's the B31xx, yes that is grass in the middle! Also would it be able to reverse as quick as a local on meeting another vehicle?

Think of the lives that could be saved by driverless cars though. Once the technology is available shouldn't saving lives take priority of wanting to drive yourself?

How would a driverless car be able to cope in a situation where a person, unseen, jumps out between two parked cars on a busy street? I just can't see it being able to detect, analyse and react faster than a human.

Maybe not right now but in the future it's likely that computers will be able to do these things better than humans can.

Presumably there would be a manual drive mechanism for the inevitable sensor failures? Just look at what can happen in modern multiplexed vehicles, we had an engine mis-fire that was caused by a faulty fog light switch pumping dodgy voltages into the multiplex. Now what if something like that started pumping voltages into the multiplex and caused the car to go haywire. Of course common sense would mean it would shutdown, but then how do you recover the passengers and the vehicle and avoid the jams?

Yes but I would expect it would basically be a joystick to allow the car to be moved at a slow speed to a safe place.

I'm curious to know if you drive? If so, did you have to do the hazard perception test?

I'd be interested to know how you propose having a computer that can calculate potential risks developing, many of which will lead to nothing, and then deciding whether it needs to take action or not. Like, at what point does the computer take action? Hazards develop at different rates and in different ways.
What about risks the computer has not encountered before?

Also, I wonder how a computer would react to a high speed blowout? Or losing traction in bad weather? Breakdowns? Aquaplaning? Snow? Ice? Spillages?

Now that I drive a faster car, I generally drive slower to conserve petrol. If I stick to 60-65, I can average 45-50mpg on a good motorway/A road run. It drops to 30-35mpg if I'm doing 80-85mph. i used to drive the M1 during 2am-6am, if lorries are restricted to 60, then most of them must be overridden as I've seen them racing each other and I've struggled to overtake doing 80.

To the original poster who said speed kills, why do the unrestricted Autobahns have some of the safest figures when it comes to casualties and accidents? And some of them are no more than dual carriageways.

Also even if there is no legislation from banning the manual driving of cars on public highways, the insurance companies could simply make it unaffordable.

On some of the better motorways in France/Spain the speed limit is 130 kmh (80 mph). I suppose this is safer in France as the motorways over there are considerably quieter than ours. Roughly speaking France is twice the size of the UK & has half as many people living there.

It's time for some righteous indignation people......

I travel on the motorway as fast as the traffic and weather allows me. If it is clear, I will drive at an average of 100 - 110mph (indicated + slowing down for any potential risks ahead), if busy I don't accelerate between lane hoggers and just stay at whatever the speed of the traffic is.

I always drive exactly to the conditions, if there is nothing, it is clear and dry, I have been known to get up to 140mph in my saab. I once got up to 155mph on the autobahns in a merc E class and 160mph on the Nuerburgring Nordschleife. (btw the picture is my friend crashing the S2000, not me!)

So now you've all choked on your tea, let me just say that I am a very experienced driver and have been professionally trained. I DO NOT drive as fast as I can all the time, it is only very rare that I push the car to see what it is capable of and to clear out the valves and turbo.

Love and Peace to all :)

Fair enough, as long as when you do get collared for doing 50% over the speed limit, you don't wail 'Woe is me, I'm so hard done by'.

So you drive at those sort of speeds because you are experienced and have been professionally trained. Well good for you, let's hope for your sake everyone around you is up to your obviously stupendously high standards otherwise one day your luck will run out. Trouble is you will probably take out some other innocent person with you.

As I said, anyone driving at over 100 mph should get an automatic ban. There is absolutely no excuse for driving at this speed and putting lives in danger.

as if? Besides, it happened years ago so been there, done that

Theres a difference between proffesionally trained and arrogance...

already did, was banned years ago for doing 117mph late at night when dry with no-one on the roads. I have no problem with this, If I get caught, its a fair cop guv.

I actually find that driving at 50 - 70 mph is MORE dangerous on the motorway than 70 -100mph. Why? because mingling with the numpties/grandparents/fearful actually creates more incidents, some of the manoeuvres I have seen beggars belief, so I stay away from it.

But please, keep em coming if you can ;)

Michael Schumacher was a very confident driver on the race track but he still had a few crashes. Your reckless driving is putting the lives of other people at risk.

So you have been banned once and still continue. Well done for not learning your lesson.
Lets hope you get another one soon

Yeah but at 50 you got more chance of avoiding / surviving an accident than at 100

Exactly. And even highly competent drivers should have NO experience of estimating what a plonker shooting along at those speeds looks like in their mirror. Or even the startling effect on concentration of being overtaken by someone doing twice their speed when they are at the limit. If you truly are "professionally trained", then I would have though the most professional way to drive is within the law.
