I understand what you mean Andy. The four lane here is 50 mph anything over 55 you will get a ticket. So really no fast lane. You could be the only car on the road in either lane and the will tailgate you. I see many cars every time I am out getting tickets. The amount of wrecks here a couple of years ago almost cost the county some state grants so they have been hot with the radar..
You can only drive as fast as the traffic in front of you in the fast lane or left lane. Most of us know there is always a couple of cars or a semi running one mile an hour faster then the semi he is passing...
I did the same thing and I have a great music collection back when legal. I may have bought 5 cds from Amazon in 7 years. all the Sears retail stores all closed here and in other towns 2 years ago. You can buy speakers home and car from Crutchfields and you to have a money back guarantee..
