How's the drive from Frankfurt to Prague. For fun, I'm thinking of doing it next month vs. flying. Google says 531 km, which it estimates at 5 hours. Can it REALLY take that long. I certainly don't plan on driving only 100 km/h. There are no more border checks, I assume? How are the highways in CZ? Seems about 150 km of driving on that side of the border. I like to drive, but this is just an overnight trip, so...
