To emphasize just how fast this is in comparison to regular rail:
When I was visiting France some years back and took the TER train on the way from Paris to Strasbourg (300mi / 500km), and that crawled. On the way back, we took the TGV, which flew.
If you look at booking tickets on SNCF's website, the difference is stark: about 5 hours via the TER, versus a little under 2 hours via the TGV. (From that perspective, it's a little funny to describe the TER as crawling, seeing as that's not meaningfully different from driving that distance.)
There are some portions of Amtrak that have comparable max speeds (notably, the Acela) but even then, the average speeds on those routes are nowhere near 200km/h.
I took the TER from Strasbourg to Paris just weeks ago (just 2 3rds of the distance for me because I was not in Strasbourg). It travels well over 100 km/h all the time and it makes only a few stops. That is only half or even less of the TGVs' speed, but still faster than by car. Definitely not crawling.
As I mentioned -- it's not actually slow in absolute terms! The experience is lodged in my mind because it took so much more time than the reverse trip, and it was sweltering to be stuck on a train with inadequate air conditioning on a rather hot summer day.
There are of course many benefits to taking even the TER over driving the equivalent distance: you don't have to be laser-focused on driving (especially in a foreign country where you might not speak / read the language or necessarily know the rules of the road), you don't have variation in travel times due to traffic (which, by driving, you would only contribute to), reduced per-passenger emissions, and so forth.
