A car is a good way to explore the countryside, especially places not connected by rail, such as Veluwe, parts of Zeeland and The North Sea islands. The motorway network is extensive, though heavily used. Congestion during peak hour is usual and can better be avoided. Roads are well signposted. Driving is on the Right side. When driving in cities, always give priority to cyclists when turning across a cycle lane. If you are involved in a collision with a cyclist, you will be automatically liable (though not guilty) unless you can prove that the cyclist was in error, in which case you will be deemed half liable. If you can definitively prove that they were both in error and trying to hit you, and the person hit was 14 or older, they will 100% liable. If you wish to see only cities, a car is not the best option. Due to limited road capacity and parking, cars are actively discouraged from entering most bigger cities.
P+R park and ride facilities are available at the outskirts of bigger cities; you can park your car cheaply there, and continue your journey via public transport (often free or with a discount when you have parked at the P+R).
Road signs with directions are plenty, but having a map is useful, especially in cities where there are many one way streets, and getting from one part of the city to another is not always so straightforward. Be careful not to drive on bus lanes, often indicated with markings such as Lijnbus or Bus, nor on cycling paths, marked by the picture of a bicycle, or by a reddish colour of asphalt.
