I find that some drivers, usually in a one lane road, tend to take the middle and do not signal. Are you going straight? Right? Left? Meanwhile, there is a line of cars behind you waiting on you for your next move. Remember to signal to let others in on your big secret.
Here is an idea that may be helpful. If you are going to make a left turn...stay to the left. And, and...get this, if you are going to make a right turn...you guessed it, stay to the right. Remember to signal to let others in on your big secret.
Just because you are Asian, does not mean you have to drive like one. And if you are not Asian...you have no excuse.
