One thing I do think that will be incorporated in a propelled vehicle is a device that you have to provide a sample of alcohol or drug use before your allowed to drive!

Ah!but what if you were out the night before and went an Indian and had a vindaloo that turned your stomach upside done,thus needing an urgent almost immediate plan of action! We have all been there.
Human after all.
Well…there is already no problem with long distance motorcoaches,such as those in service with the
well-known and nationwide National Express company,and other motorcoach operators that provide
day excusions and motorcoach holiday tours,since their motorcoaches are equipped with toilets 
Toilets were first fitted in motorcoaches in the 1920s.
If you have over indulged yourself with food and booze the previous night,you surely will be in no fit state
to make even short distance journeys,never mind long distance ones 
And probably in 2114 people will be more in tune about what they can and cannot eat and drink - and the amount that they consume. So that
over indulgence will be no problem ,but if they want to get kalied ,you’ll just have to get bombed
during extended leisure hours-periods,i.e.long weekends and holidays - and a full 24 hours will elapse before you are allowed go back to work .
However,and bear this in mind,the cabs of lorries were pretty basic at one time,but they gradually improved
with really comfortable seats,air conditioning,sleeper bunks,provisions for microwave ovens,television sets,
etc.So in the future,the lorry manufacturers might fit built-in toilets in the cabs just like in motorcoaches.
Delivery times could be improved,since the overseer driver could use this facility while the lorry continues
it’s journey without having to stop at the motorway services
But of course,if their is a real emergency for whatever reason,the overseer driver just presses the Emergency Stop button,and the motor vehicle will pull over on to the hard shoulder and stops without any disruption to any of the other motor vehicles. Since the onboard computer of each vehicle will be in constant communcation with each other,and will know what each vehicle within ,say a third of a mile,is doing and will therefor take corrective and/or evasive action
All motor vehicle control-drive computers and town and city motor vehicle control computers will probably have back up systems and double back up power systems. The beauty of having automated-remotely controlled motor vehicles is that they will virtually eliminate road traffic accidents

Yes that’s all well and good but what about emergency action ?
We might get vehicles like was in the “Fifth Eliments” with Bruce Willis.
Evening Gentlemen, well there I was, all ““dolled up”” for an important function at the Sofitel in Lyon, May 1978, urging my, (very basic) Renault 12TL down through Lyons tunnels, suddenly, ahead I spotted a UK registered coach, I accelerated, (not an easy feat in a little Renault)! untill I was behind the coach.
Suddenly, WHOOSH, the whole front of my car turned from yellow, to brown!!! Now who was the B…d, who pulled the flap, and emptied the toilet■■?
I believe it was a common trick amongst our PSV “friends”.
Today I received a lengthy document from our good friends at John Deere, inviting me to a demonstration of "Drone"Technology. I am assured that my future will be sitting in one tractor, with umpteen others mimicking my every move…Gentlemen I do not fancy it at all!!!
Cheerio for now.
Digital eh,where did it arise from?seriously

THE “DRIVER” IS ENJOYING A GAME OF CARDS WHILE THE MOTORCAR DRIVES ITSELF.
I once saw an article,maybe in an old EAGLE ANNUAL from the 1950s or 1960s,about The Motorcar Of The
Future,and one of the illustrations showed motorcars travelling along on a motorway.In the nearest automobile (the drawing portrays the rear view of the cars),the “driver” and his passengers are all sat round a table enjoying a game of cards,or whatever,while the motorcar drives itself
EUREKA! 
NOW THAT’S WHAT I’M TALKING ABOUT! :-
This illustration is from the PALEOFUTURE Website and is entitled Driverless Car of The Future 1957:-
paleofuture.com/blog/2010/12 … -1957.html
And I’m sure that this illustration is the actual one that I saw in an Eagle Annual,or something,in the 1960s
It’s brilliant!

Carl Williams:
I can’t help but think the future of all vehicles will be propelled by four electric motors driving each wheel. They would obviously need a reliable smallish diesel engine ticking over to power generators to keep the batteries charged to power the electic motors.From the experience of showmen we already know what are the best diesel engines to power generators. So perhaps ‘come back Gardiner, all is forgiven’.
However more seriously to help the engine, and increase efficiency, such things as windpower, and the power lost whilst braking can be used also for box and curtainside vehicles solar pannels can be used on the roof to create more energy. It is not impossibe that fuel efficiency of up to 100 mile per gallon or foreign measurement per foreign measument as we will be using by then will be easily possible.
As the vehicle goes forward wind resistance could be cannelled into turbines to generate electricity. That is what I mean by windpower.
With the exception of the solar panels all the rest there seems to forget that you can’t get more power out than you put in although it’s going to take more than a trailer roof’s worth of solar panels to make a worthwhile addition to the electricity supply required in addition to the expense.That’s on a sunny day let alone a cloudy one.In the case of those electric motors you’ll actually need an engine that produces more power than the electric motors at the wheels provide because of the electric generation and transmission losses in what is effectively just a diesel power pack/electric transmission system with a battery storage back up.So at modern day power output expectations that old showman’s Gardner engine powering the gen set will need to be putting out around 500 hp + . 
While that windmill on the roof will only,at best,provide as much power for extraction as the aerodynamic drag that it creates to get it,again then having to allow for generation and transmission losses. 
All of which probably explains why we’re not seeing loads of diesel/electric wagons with great big windmills bolted to the cab roof pulling curtainsiders or box trailers with roofs covered in solar panels using already available technology. 
Which just leaves the idea of hydrogen powered trucks and cars that drive themselves all travelling at 56 mph max.What a boring zb world that’s going to be for the unlucky future generations. 
Meanwhile luckily we’ve still not gone too far from the good old 20th century and the world as we know it just yet.
Yes but it could be a hybrid, electrical when going slow & in towns so you didn’t have to pay emissions charges,and have plenty for TV’s Laptops, and cooking your salads and a big bonus if you electrify the load, any looters that tried and got away, the police could pick them out, because their hair would be standing up!
