Not on the stretch between Mainz and Kaiserslautern. Besides, unlike Americans, Germans know how to control their cars. I was going slow to conserve gas. At $6.00 a gallon it is not cheap. The Euro is overpriced, and we wanted to waste our money on other things.
That's the truth. They actually use turn signals. I travel to Ingelheim at least twice a year. I wish German rules of the road were enforced here.
