You know those traffic lights they have on onramps to help space out traffic and supposedly make it flow better?
I call bullshit.
I think they are designed to make traffic slow down instead.
Think about it, usually you have to stop right at the start of an onramp giving you little chance to accelerate to traffic speed. Unless you floor it and have a V8 you arent going to get up to the 55-65MPH needed to meet traffic speed. So that forces the entire right lane to slow wayyyyy down to let those people onto the freeway, and that causes the freeway to slow down.
