A man has been seen driving a Fiat 500, it has emerged.
Police are now keen to speak to the male motorist, fearing he may be in need of medical attention.
The sighting happened on the B1083 near Alderton in Suffolk on Sunday morning.
Officers say the man with Fiat 500 may have deliberately used quiet country roads to avoid being recognised.
“His plan backfired when he was spotted behind the wheel by a passing cyclist,” a Suffolk Police spokesman explained.
“He was heading towards Woodbridge, where he undoubtedly intended to park in a quiet field outside of the town and walk the rest of the way.
“There is a remote possibility that he could not care that anyone saw him, in which case we’d like to speak with him to make sure he is okay.”
The police were called when the concerned cyclist stopped at the Alderton village shop and asked to use the telephone.
It has been legal for women only to drive the Fiat 500 since it was relaunched to widespread acclaim in 2007.
A Fiat insider said: “We often get males in the showrooms looking around – but only when they are with their wives or girlfriends.
“They often remark about what nice little cars they are but decline the offer of taking them out for a test drive.”
Women can buy a new Fiat 500 from only £10,700. They are available in a range of colours, so long as it is white.
