I did 32hrs of driving not sure how many km it was, but the coastal highway 1 is 50kph double yellow line. I know of a couple who get on the Greyhound and go from West Coast to Ontario, its like 50 hrs and I have never been able to sleep on the Greyhound without a bottle of vodka even then its a rough sleep. Plus now a days they search your bags so you gotta be skillfull. I only really do 18hrs on the dog. My Fort McMurray trip is about 750km and I do that in one go.

I think it should take me around 7 hours time with around 3-4 breaks in between the drive. but well... german Autobahn... you never know what to expect. Can you do highspeed, or can you just go around 120 km/h there should be 4 road constructions on the way with around 60-80 km/h. 

Well I shall see. once it took me around 7 hours, another time it took me around 13 hours... 

I think you can go as fast as you want in fast lane. In Montana you used to be able to do the same during daylight hours.

Its what 8 hrs ahead or is it 9 hours ahead. Traffic would explain extended driving hours.

not anymore. the most part of the way there was a 120 km/h max limit today. 

It took me 11 hours to arrive, the funny part, the way through the construction sites were the best parts. Outside of those I was in many traffic jams. 3 due to accidents, one big one and 2 smaller ones, the big one happily only car damages, no persons harmed. but well about 8 cars involved, i could see as i drove by... due to that 2 from three lanes closed...

whiplash is subtle, thats why you need to sue them on the spot
