Give or take. There's plenty of trains between countries in Europe that would also be within driving distance.
In my mind, the optimal realistic situation is to have rail for longer distances (1-8 hours), but not trans-oceanic obviously, and then either ICE or local light rail for smaller trips
The relevant point is that there are no (or very few) international ICE trains. Cross-border are usually slower Euro-city trains that shouldn't be included in the ICE statistics.
