Over half of business drivers aged 25-35 are concerned that they will be replaced by driverless cars in their working lifetime, according to research from Masternaut.

In this age group, over half (55%) said that they will be replaced by driverless cars, however, drivers over 35 are less concerned. Only 34% of 35-44 year olds and 12% of 45-54 year olds are worried that autonomous vehicles will replace them.

With driverless cars currently being trialled in Greenwhich, Milton Keynes and Coventry, the road to autonomous cars is already being well tested. Ministers are currently considering changes to the Highway Code, which would allow driverless cars to be used by the general public.

Despite trials being underway, many business drivers believe that the biggest barrier for driverless cars will be the integration with regular vehicles (41%).

This group also believe that barriers such as improving road infrastructure (37%) and insurance and liability issues (34%) will hinder the implementation of driverless cars.

These are not the only stumbling blocks that business drivers think will affect driverless cars with 30% believing that changes to driving regulations will present a big barrier.

Steve Towe, Chief Commercial Officer and UK Managing Director, said: "Driverless car technology is a very exciting development for the automotive industry and represents a major step change for UK roads, one of the biggest changes in history."

"Previously a science fiction dream, driverless cars are now very real and are being tested on our roads, and we’re intrigued to see what the future holds for the technology."

"It’s very important that in order to get the true picture on the future of driverless cars, that we consider the potential impact on a very important group of stakeholders; the business driver, the people who use the roads every day as part of their job."

"We haven’t heard a great deal from professional drivers on how driverless car technology could affect them in the future, which is something that needs to be taken into consideration, especially considering that to date in 2015, 56% of new vehicle registrations have been fleet vehicles."

The survey noted that 15% of professional drivers would not like to work with autonomous vehicles and would change jobs. While 23% said they wouldn’t like it but would stay in their job and 9% said that they would prefer working with autonomous vehicles.

It was found that business drivers in London and York are the most worried about the technology, with 40% of drivers concerned that they’ll be replaced in their working lifetime. The least concerned areas are Bristol, Liverpool and Sheffield.

The survey asked 2,000 UK employees who drive as part of their job in order to discover attitudes towards driverless cars.
