A two lane RA works esp good if you want to make a left turn. Enter the RA and get in the inside lane as soon as it is open. You can pass all the other traffic that is using the next two exits.
Merge back into the outside lane and exit.
Sarasota has a section of 'The Trail' that has three intersection in a row with two lane RA's.
There is only a city block between each one. The gray hairs really make it fun.
