1) whom do I call if I am involved in an accident? Do I call the police (999)?
2) what happens if I give the wrong amount when I get out of the tunnel? E.g. instead of giving $8 I give $6 by mistake? I almost did last week.
3) how many liters per km do you consume? My car (Nissan Note) was advertised as doing 25 km with 1 litre, but I think that's what it consumes in the highway
