I was born in Germany and have been back there many times. I always rent a performance type car, BMW, megane, Gti, The freedom on the autobahn is breathtaking. The average speed in some areas is 100mph. I have personally done stints there at 138 mph...pretty much top speed of the rental car (would love to have my corvette or porsche there). Anyhow, in NJ and pennsylvania, where I live, the average interstate speed is now 80 mph...if you stay in the left lane and follow traffic, you must do about 80. I have had shorter stints at 90+ and even hit 115 quite easily in my gti. I love the way this car drives at those speeds...that's the german engineering and attitude.. Its a shame US drivers are so undertrained, because you run into many situtations where people are going too slow in the left lane and they stay there indefinitely, backing up faster traffic behind them and causing very unsafe situations. On the autobahn, if you do this, you will be run off the road...keep right , pass left is the religion. I was in a situation once during a heavy rain, still driving about 100 and I couldnt get over to the middle lane because of traffic and was being tailgated by a driver that approached me at about 140...finally got over to my relief. Anyhow, driver training needs to be upgraded in this country...this is what makes fast driving safe.
