Although I applaud the developing technology of driverless vehicles for its safer driving and evironment protection I cannot help but wonder about other effects.

The idea of a platooning lorries raises images of being stuck behind such a convoy travellling at 40 mph on minor roads, not being able to join a major road, access a roundabout or join/ leave a motorway.

Dual carriageways reduced to single carriageways, and three lane motorways to two lanes.

Our roads are already have more pot holes per mile than a collander, with many inside lanes with deep grooves erode to lorry width.

We already have such a system of cargo carriage – freight railways! This technology maybe suited to large continents, even some European countries, but not here in the UK.

Our infrastructure is just up to it – even with massive investment.

Think again Mr Cameron.
