Green bike lanes?

What colour should the bike lanes be?  That was one of the main topics of discussion at last night's city council meeting.  Councillor Aldo Ruberto brought the subject up suggesting the bike lanes should be a different colour than the white traffic lanes.  Councillor Iain Angus isn't in favour of changing the colour; he says its a waste of taxpayer money.  Ruberto feels if the bike lanes were green seniors and others would be able to easily identify what lanes you can drive in.
