Last week's Budget confirmed the UK will begin to trial driverless lorries and cars.
The government confirmed "lorry platooning" trials where vehicles in convoy headed by a driver in the leading lorry will go ahead.
It also announced that driverless cars will be trialled on UK roads by 2017.
The government said it wanted the UK to be a "global centre for excellence in connected and autonomous vehicles".
President of roadside recovery firm AA, Edmund King, questioned the practicality of a lorry platooning scheme in the UK.
He said: "The problem with the UK motorway network is that we have more entrances and exits of our motorways than any other motorways in Europe or indeed the world.
"Therefore it's very difficult to have a 44 tonne 10-lorry platoon, because other vehicles need to get past the platoon to enter or exit the road."Return to internet news headlines
