In the suburbs or even smaller cities, driving is still faster. Hell, the trains here hardly have time to accelerate past 120kmph so driving can actually be faster than the train too unless you are going directly from city center to city center (most people need a 10 min bike ride on one or both sides).
Even If North America starts taking transit seriously, the routes needed to connect the suburbs to most metro downtowns will be enormous. There will either needs to be hundreds of bus routes feeding into light rail, or perhaps better bike infrastructure can get people close enough to one of dozens of light rail stops.
In any case, sprawl is currently setup to make urbanizing a slow and painful future for transit enthusiasts.
I was just rarely traveling to other city centers, and some town or forest isn't going to have a time competitive public transport options.
Hell, the Flixbus Amsterdam-Maastricht (station to station) is faster than the train. It has a lower top speed, no direct line, but it just doesn't stop 7 times or so in between.
If the Netherlands wants to continue to be competitive and ease the housing crisis, the trains need to be faster and cheaper so everyone can spread out and not be forced to spend 3 or 4 hours a day commuting to work if they live in a different city.
NL public transport is super expensive. Doesn't mean it's never interesting, but when I lived in France near a TGV station, I took the train much more often. It did often have both speed and price advantages.
Where things really shine is high-frequency, high-speed rail plus bikes. The IC Direct Rotterdam-Amsterdam is fast enough that I used to go from my place to my sister's, door-to-door, in about fifty minutes by bike+train, versus typically around a little over an hour for a car.
If you want a really impressive ratio you have to look to the TGV; in college I did Marseille-Paris, Paris-Lille, Lille-Brussels often and each of those segments are three times faster than the car!
Car dependency is a choice. Even in Europe the norm of cars is strong.
That argument can be made everywhere even with perfect public transport.
Where I grew up (London) public transport was usually faster than driving.
