This subject has been mooted for for a century.
A quote from Sir Herbert Austin, almost a hundred years ago:
My other little bit of advice, chiefly tendered to the younger generation is: Be courteous. I do not address this to the younger generation because I think they are any less courteous than were their fathers, but because they have to carry on the good work. They were born with a steering wheel between their hands, and it is up to them to see that throughout their lives they are able to make the very best use of it. If motorists will practise a perpetual courtesy then will the motor car establish itself still more firmly in popular favour, and primitive legislation, which still hampers development, will be swept away. Common sense' and courtesy are the qualities required to make motoring safe."
