Yeah, that's pretty accurate, I'd say that population-weighted for the Netherlands the average is around 2x. If you're in rural areas it can easily be 8x or worse (2 hours for a 15-minute drive.)

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!
