I knew the guys goal was 1000 miles in a day but he quit after arriving at his hotel because he had plenty of charge and time to drive the extra 27 miles with plenty of time left in the day but he did not feel the need to drive it to comfortably say 1000 in a day is doable with an EV.  Sorry about that, I got his numbers swapped with a 700+ mile, 22 hour start to finish trip I did, granted 7 hours were spent not driving 1/2 thru the drip.

For me the thing is most trips do not involve a significant amount of interstate because I do not see a need to add 150-200 miles to a trip just to drive on the interstate.  In the last year I have had several days where I have driven 5-600 miles and never even driven on the interstate.  The reality is very, very few people will drive 11 hours+ straight only stopping for fuel.  At some point you need to get out and stretch, find the need to take a 20 minute power nap, or just sit down at a restaurant and eat a meal.  I have driven on long trips with a few guys and they always want to stop for something while I have no problem driving straight thru to a destination 2-300 miles away.

Now I appreciate you trying to downplay EVs but your example, but you should consider that HOS requires a minimum 30 minutes (consecutive) non driving in the first 8 hours; HOS drivers cannot legally drive 11 hours straight thru.
