one should also realise that european continental trucks have a speed limiter, officially set at the legally allowed 80 kph, but mostly somewhere between 85 and 90. This is fully at odds with my experience in the USA where putting the cruise control at 70 mph, you will be regularly overtaken/blown aside by trucks. For us thererfore a truck is something that you want to pass as quickly as possible rather then getting stuck behind it.
