I just drove from TX to NY last week in a Model Y with no range/charging problems.
I stopped about every 2.5 hours which may be a bit shorter than the average person's leg in an ICE car but is about as long as I personally want to remain sitting down.
The Tesla charger network is incredibly reliable, the Model Y's cold weather range is pretty darn good relatively, and I had zero charger wait times the whole way.
I'm glad to hear Tesla is opening up its charger network to others and am looking forward to the V4 chargers with longer cables. My only wish is that other EVs had the same connector because the Tesla one is so much slimmer.
SpaceX and Tesla cannot move with the ease of software companies due to the facilities and equipment needed to build, test (and in SpaceX's case, launch & land) their vehicles.
