The positive effect of road is almost everywhere ruined by the lower density that car-based city planning cause, and by traffic. Sure you can move good farther and faster, but in fact you're still supplying the same amount of people and companies, so the net effect is zero. It can only work if you're: - space-constrained so your urban density doesn't reduce because of cars - have very good public transportation so that most people stay off the road no matter what, otherwise traffic makes your cars too slow to bring anything. These conditions are almost never met, but maybe they are in the Netherlands as an exception to the rule.
