Technology alone will not reduce carbon emissions, according to the Low Carbon Vehicle Partnership.
In a warning to UK residents, the advisory group said that people will need to change their driving habits as well as embracing new technology if tight government targets on CO2 reduction are to be met.
Neil Wallis, head of communications for the body, commented: "It's not going to be one or the other. We're going to need a technology shift and a certain amount of behaviour change too."
He went on to say that technology could help people alter their driving practices, particularly if it is an initiative that makes life easier.
Last month, information about an EU project that hopes to develop vehicles that drive themselves was released.
The concept aims to create convoys which travel along motorways, with a professional driver in the lead vehicle directing those behind that would be controlled through a sophisticated communication system.
Cutting down on drag is a significant focus of the scheme, which could lead to a 20 per cent saving in energy, which would be passed on in the form of reduced carbon emissions and more cost-effective travel.
