Driverless Ford tackles snow problem

Motoring giant Ford says it has conducted successful tests of its driverless cars in snowy conditions.

The company said it had been running sensor tests for more than a year, but was now driving autonomous cars in a controlled, snowy environment.
Snow presents a challenge to driverless cars because the sensors they use to detect road markings and hazards do not work well in wintery weather.
Google has also been testing its autonomous vehicles in the snow.
