A west London road may be stripped of its kerb, traffic lights and signs in an attempt to encourage pedestrians and cars to mingle.
Traditional traffic controls would be stripped away
Exhibition Road in Kensington could be the showcase for the "naked road" experiment - pioneered in Holland.
Organisers say the idea works as a form of psychological traffic calming which encourages drivers to be more considerate to pedestrians.
But an RAC spokesman said it may encourage drivers to be more reckless.
RAC Foundation executive director Edmund King said: "This is a form of psychological traffic calming which encourages drivers to slow down and think a lot more about pedestrians and other road users.
"We shall be following this trial very closely.
"In Holland, there have been places where a number of roads meet and no one
has the automatic right of way. Although this might make drivers more careful,
it could also encourage the aggressive motorist to behave more recklessly.
"We would certainly question whether this type of experiment should be
implemented on a wider scale."
Exhibition Road, home of the Science, Natural History and Victoria and Albert museum, could have a maximum speed limit of 20mph and drivers will not automatically have right of way over pedestrians who will be able to cross anywhere on the road.
Kensington and Chelsea Council, the lead authority on the project, said the scheme was part of a number of traffic calming proposals and a decision would be made in the next few months.
A similar naked road scheme is already in place in Wiltshire.
