All I did was add statements inside of the sentence giving reasons for why each of the points was made in an attempt to clarify why you made each point and to show that none were directly related to another. Simply adding numbers wouldn't necessarily communicate that to someone.
Did you, like Helmet Head, believe that I was asserting that the beginnning of the dashed line determined where cars can enter the space?
Why would I put a comma in between each clause?
Wouldn't believing that the dashed line is what determines whether a car can enter the space, mean that I would think that cars are not legally allowed to cross the bike lane when it is solid, like at the many driveways I ride past in San Diego?
By the way, the 3 items are related. The 3 conditions are all required to be present at an intersection where a right turn is allowed.
