There is one thing I hate worse than someone who merges into my lane without giving me notification by using their turn signal. That thing would be someone who does not use a turn signal and straddles both lanes while they are trying to decide which lane to be in. Even worse than that is when the person is in both lanes they are only going 20mph. in a 35mph zone.

While you are straddling both lanes do not get the idea that I am slowing down because I actually want you to merger into my lane. The reason I am slowing down is because I do not want to be sideswiped while you are try to figure out where the hell you are and what lane you want to be in.

The correct procedure for driving is to pick the lane you want to be in and stay in it. If you must be in another lane make sure you want to be in a different lane, give adequate notification to the drivers already in the lane by using your turn signal and then merge in to the lane when there is enough room to safely merger between cars. The incorrect way is to straddle both lanes and then decide what you want to do.

You have now been informed, so no more straddling the damn lanes.
