I have been watching one of those American programmes about guys in vans trying to buy tat to sell at a profit, only I was looking at the roads rather than the tat. Then I had a look on Google Earth at a few Midwest American towns laid out in neat grids, as is the whole countryside.

What I failed to see are roundabouts on American roads.

So if driverless cars are designed for roads without roundabouts can the be used on UK roads?

When four cars are pulled up at the white lines on a roundabout one of the drivers has to sense what the intentions of the other drivers are from their positions on the junction and visual stimuli from trying to make eye contact or just checking they have looked your way, so are aware of your presence. This may be aided by the use of turn indicators, though some drivers don't seem to know what the lever on the steering column is for.

Can technology designed for roads without roundabouts cope with these on UK roads and spot the safe opportunity to pull out?

In America they have the four way stop, where by convention you can move on in the same order in which you arrive and stop. Obviously if two cars arrive at exactly the same time at the four way stop there is a potential stall or crash condition for driverless cars or mixture of human driven cars and driverless cars.

It would be interesting to see how a driverless car negotiates the Plough "Magic" Roundabout in Hemel Hempstead which breaks all the usual rules for roundabouts in the UK.

Just wonder what they will do at a figure of 8 mini roundabout. I am thinking of working on an internet of things security blocker to stop hackers trying to reprogram the cars computer; to drive on the left instead of the right. Hummm !!

Will UK driverless cars have the ability to swop to driving on the wrong side of the road for Continental holidays?

Also will they be able to tow a caravan?

I can't foresee a time when lads in their late teens don't want to drive a car themselves or when a driverless car can complete most journeys.

Caravans are not the only thing on the road ill suited to automation.

I presume showmen still have their own driving licence category allowing them to take road trains with multiple trailers onto UK roads as the tractor unit tends to have a generator mounted on it and tow using a drawbar rather than it being set up as an artic.

Another though that came to mind is that people driving cars will cut up driverless cars making the assumption that they will automatically activate the other cars brakes, though is that already possible with some cars?

Also will you be able to get the driverless car to drop you off the airport to go on holiday, then return home alone to wait for you to return a week or so later, before coming to pick you up again?
