Pros
People get out of the left lane, period. The way it should be. You can’t appreciate the difference without experiencing it
No need for stop signs at every intersection, when a yield sign will do (even at the end of an off ramp)
High speed limits – not actually unlimited unless you’re far from a city, which in a small densely populated country…
Cons
Super expensive gas @ €1.50/L ($2/L or $7.60/gallon)
No right turn on red
Slightly confusing highway direction signs
