I guess its difficult for you guys in the US as you don't have the lane specific requirements we have here in the UK. Our first lane (inside lane) is the main lane, and the other two (or sometimes more) lanes are for overtaking. So I can quite safely sit in the inside lane at 55 as cars will pass me in the middle lane, and faster cars pass them in the outside lane. So I can be at 55 while others are 90+
