Now THAT's cool (head works near perfect I reckon) - just needs faster print IMO:

print was never written to print massive data sets. Even if it will print only the first 99999 lines, it will first convert the whole object to text. I agree that this is annoying, but printing the table without features also takes long, and printing the table with features eventually works. As you see, sf has a format.sfi method, but it doesn't know whether it will be called 10 or 10 billion times. It does "some" optimisation, just not one that helps a lot for this particular dataset (with only LINESTRINGs).

Maybe a nice use case to try out sf with tibbles?
